## Critical Performance Issues (Fix Immediately)

### 1. **Memory Aggregation - N+1 Network Storm**

**Location**: `/mahavishnu/pools/memory_aggregator.py:167-203`

**Severity**: 🔴 CRITICAL

**Current Performance**:
```python
# Lines 183-203: Synchronous sequential HTTP calls in loop
for memory_item in memory_items:
    try:
        response = await self._mcp_client.post(
            f"{self.session_buddy_url}/tools/call",
            json={"name": "store_memory", "arguments": memory_item},
        )
        if response.status_code == 200:
            synced_count += 1
```

**Impact**:
- **O(n) network calls** per sync cycle
- Each call blocks on network I/O (100-500ms latency typical)
- For 100 memory items: **10-50 seconds** of blocking time
- No parallelization, no batching, no connection pooling reuse
- **Degrades linearly** with pool/worker count

**Optimization**:
```python
# BATCHING + CONCURRENT REQUESTS
import asyncio

async def _sync_to_session_buddy(self, memory_items: list[dict]) -> None:
    """Batch sync memories with concurrent requests."""
    BATCH_SIZE = 20  # Configurable

    # Process in batches
    for i in range(0, len(memory_items), BATCH_SIZE):
        batch = memory_items[i:i + BATCH_SIZE]

        # Parallel requests within batch
        tasks = [
            self._mcp_client.post(
                f"{self.session_buddy_url}/tools/call",
                json={"name": "store_memory", "arguments": item},
            )
            for item in batch
        ]

        responses = await asyncio.gather(*tasks, return_exceptions=True)

        # Handle responses
        for response in responses:
            if isinstance(response, Exception):
                logger.error(f"Batch sync error: {response}")
            elif response.status_code == 200:
                synced_count += 1
```

**Expected Improvement**: **10-50x faster** (50s → 1-5s for 100 items)

---

### 2. **Pool Memory Collection - Sequential Blocking**

**Location**: `/mahavishnu/pools/manager.py:282-319`

**Severity**: 🔴 CRITICAL

**Current Performance**:
```python
# Lines 310-317: Sequential async calls
for pool_id in pool_ids:
    pool = self._pools.get(pool_id)
    if pool:
        memory = await pool.collect_memory()  # BLOCKING
        aggregated[pool_id] = {
            "memory_count": len(memory),
            "status": (await pool.status()).value,  # BLOCKING AGAIN
        }
```

**Impact**:
- **O(pools × memory_collection_time)**
- Each `collect_memory()` may take 100-1000ms (depends on worker results)
- For 10 pools: **1-10 seconds** blocked
- `pool.status()` called twice per pool (duplicate work)
- No caching of status information

**Optimization**:
```python
# CONCURRENT POOL COLLECTION
async def aggregate_results(self, pool_ids: list[str] | None = None) -> dict:
    if pool_ids is None:
        pool_ids = list(self._pools.keys())

    # Collect all data concurrently
    tasks = []
    for pool_id in pool_ids:
        pool = self._pools.get(pool_id)
        if pool:
            tasks.append(self._collect_pool_data(pool_id, pool))

    # Execute all in parallel
    results = await asyncio.gather(*tasks, return_exceptions=True)

    # Build aggregated dict
    aggregated = {}
    for pool_id, result in zip(pool_ids, results):
        if isinstance(result, Exception):
            logger.warning(f"Failed to aggregate pool {pool_id}: {result}")
        else:
            aggregated[pool_id] = result

    return aggregated

async def _collect_pool_data(self, pool_id: str, pool) -> dict:
    """Collect memory and status in parallel per pool."""
    memory, status = await asyncio.gather(
        pool.collect_memory(),
        pool.status(),
    )
    return {
        "memory_count": len(memory),
        "status": status.value,
    }
```

**Expected Improvement**: **10x faster** (10s → 1s for 10 pools)

---

## High Priority Issues (Fix Soon)

### 3. **Memory Aggregation - Polling Overhead**

**Location**: `/mahavishnu/pools/memory_aggregator.py:66-90`

**Severity**: 🟠 HIGH

**Current Performance**:
```python
# Lines 80-87: Inefficient polling loop
async def sync_loop():
    while True:
        try:
            await self.collect_and_sync(pool_manager)  # Full sync every cycle
        except Exception as e:
            logger.error(f"Memory sync error: {e}")

        await asyncio.sleep(self.sync_interval)  # Default: 60s
```

**Impact**:
- **Full collection + sync every 60 seconds** regardless of actual changes
- Wasted CPU/network on unchanged data
- No event-driven updates (push vs pull)
- Default 60s interval too frequent for large deployments

**Optimization**:
```python
# EVENT-DRIVEN + DIRTY FLAG
class MemoryAggregator:
    def __init__(self, ...):
        self._dirty_pools = set()  # Track changed pools
        self._last_sync_time = {}  # Per-pool last sync

    async def mark_pool_dirty(self, pool_id: str):
        """Mark pool as needing sync (called by pools on task completion)."""
        self._dirty_pools.add(pool_id)

    async def sync_loop(self):
        while True:
            try:
                if self._dirty_pools:
                    # Only sync dirty pools
                    await self.sync_dirty_pools(pool_manager)
            except Exception as e:
                logger.error(f"Memory sync error: {e}")

            await asyncio.sleep(self.sync_interval)

    async def sync_dirty_pools(self, pool_manager):
        """Sync only pools with new data."""
        dirty_ids = list(self._dirty_pools)
        pools = {pid: pool_manager._pools[pid] for pid in dirty_ids}

        # Sync only changed pools
        for pool_id, pool in pools.items():
            memory = await pool.collect_memory()
            await self._sync_to_session_buddy(memory)

        self._dirty_pools.clear()
```

**Expected Improvement**: **5-10x reduction** in unnecessary sync operations

---

### 4. **Workflow Execution - Double Semaphore**

**Location**: `/mahavishnu/core/app.py:926-930` and `/mahavishnu/workers/manager.py:151-152`

**Severity**: 🟠 HIGH

**Current Performance**:
```python
# app.py:926 - Semaphore in workflow executor
async with semaphore:  # MahavishnuApp.semaphore
    result = await self.circuit_breaker.call(
        adapter.execute, task | {"single_repo": repo_path}, [repo_path]
    )

# workers/manager.py:151 - Semaphore in worker executor
async with self._semaphore:  # WorkerManager._semaphore
    result = await worker.execute(task)
```

**Impact**:
- **Double semaphore contention** for same work
- Reduces effective concurrency by 2x
- `max_concurrent_workflows=10` + `max_concurrent_workers=10` = **100 possible**
- But only 10 actual concurrent operations due to nested semaphores
- Wasted resource allocation

**Optimization**:
```python
# OPTION 1: Remove WorkerManager semaphore (keep only app-level)
# WorkerManager just schedules, app controls concurrency

# OPTION 2: Hierarchical semaphore with priority
class HierarchicalSemaphore:
    def __init__(self, workflow_limit, worker_limit):
        self.workflow_sem = asyncio.Semaphore(workflow_limit)
        self.worker_sem = asyncio.Semaphore(worker_limit * 2)  # 2x workers

    async def acquire(self, is_workflow=True):
        if is_workflow:
            await self.workflow_sem.acquire()
        await self.worker_sem.acquire()
```

**Expected Improvement**: **2x throughput** (10 → 20 concurrent operations)

---

### 5. **Message Bus - Unbounded Subscriber Growth**

**Location**: `/mahavishnu/mcp/protocols/message_bus.py:148-153`

**Severity**: 🟠 HIGH

**Current Performance**:
```python
# Lines 148-153: Fire-and-forget task creation
for subscriber in self._subscribers.get(msg_type, []):
    try:
        # Run subscriber asynchronously
        asyncio.create_task(subscriber(msg))  # 🔴 NO LIMIT!
    except Exception as e:
        logger.error(f"Subscriber error: {e}")
```

**Impact**:
- **Unbounded task creation** for each message
- No backpressure for slow subscribers
- Memory leak if subscribers are slower than message rate
- 1000 messages × 5 subscribers = **5000 concurrent tasks**
- No mechanism to detect/cancel hung subscribers

**Optimization**:
```python
# BOUNDED CONCURRENT SUBSCRIBERS
import asyncio

class MessageBus:
    def __init__(self, max_queue_size: int = 1000, max_concurrent_subscribers: int = 100):
        self._subscriber_semaphore = asyncio.Semaphore(max_concurrent_subscribers)
        ...

    async def publish(self, message: dict[str, Any]) -> None:
        ...
        # Deliver to subscribers with concurrency limit
        tasks = []
        for subscriber in self._subscribers.get(msg_type, []):
            tasks.append(self._call_subscriber(subscriber, msg))

        # Wait for all (with timeout)
        await asyncio.gather(*tasks, return_exceptions=True)

    async def _call_subscriber(self, subscriber, msg):
        async with self._subscriber_semaphore:
            try:
                await asyncio.wait_for(subscriber(msg), timeout=30.0)
            except asyncio.TimeoutError:
                logger.error(f"Subscriber timeout: {subscriber}")
```

**Expected Improvement**: **Prevents OOM** under load, bounded latency

---

### 6. **OpenSearch Logging - Blocking on Every Operation**

**Location**: `/mahavishnu/core/opensearch_integration.py:136-164`

**Severity**: 🟠 HIGH

**Current Performance**:
```python
# Lines 161-164: Blocking write on every log
await self.client.index(index=self.log_index, body=doc)
```

**Impact**:
- **Every workflow operation** blocks on OpenSearch write
- Typical OpenSearch index: 50-200ms
- 100 workflow operations = **5-20 seconds** of cumulative blocking
- No batching, no buffering, no async queue
- OpenSearch downtime = workflow hangs

**Optimization**:
```python
# ASYNC LOG QUEUE WITH BATCHING
class OpenSearchLogAnalytics:
    def __init__(self, config):
        self._log_queue = asyncio.Queue(maxsize=10000)
        self._batch_size = 100
        self._flush_interval = 5.0  # seconds
        self._flush_task = None

    async def start(self):
        """Start background flush task."""
        self._flush_task = asyncio.create_task(self._flush_loop())

    async def log_event(self, level, message, **kwargs):
        """Non-blocking log enqueue."""
        try:
            self._log_queue.put_nowait({
                "timestamp": datetime.now(tz=UTC).isoformat(),
                "level": level,
                "message": message,
                **kwargs
            })
        except asyncio.QueueFull:
            logger.warning("Log queue full, dropping event")

    async def _flush_loop(self):
        """Periodic batch flush."""
        while True:
            await asyncio.sleep(self._flush_interval)
            await self._flush_batch()

    async def _flush_batch(self):
        """Flush accumulated logs in batch."""
        batch = []
        for _ in range(min(self._batch_size, self._log_queue.qsize())):
            try:
                batch.append(self._log_queue.get_nowait())
            except asyncio.QueueEmpty:
                break

        if batch:
            # Bulk index
            await self.client.bulk(index=self.log_index, body=batch)
```

**Expected Improvement**: **Non-blocking**, 100x reduction in wait time

---

### 7. **Worker Selection - O(n) Linear Scan**

**Location**: `/mahavishnu/pools/manager.py:262-268`

**Severity**: 🟠 HIGH

**Current Performance**:
```python
# Lines 264-267: Scan all pools to find least loaded
pool_id = min(
    self._pools.keys(),
    key=lambda pid: len(self._pools[pid]._workers),  # 🔴 O(n) scan
)
```

**Impact**:
- **O(n) pool scan** on every `route_task()` call
- 100 pools = 100 comparisons per task
- With 1000 tasks/sec = **100,000 comparisons/sec**
- No caching of pool loads
- `len()` called repeatedly (should track incrementally)

**Optimization**:
```python
# MAINTAIN SORTED POOL HEAP
import heapq

class PoolManager:
    def __init__(self, ...):
        self._pool_heap = []  # Min-heap by worker count
        self._pool_dirty = set()  # Pools needing heap update

    async def route_task(self, task, pool_selector, pool_affinity=None):
        if pool_selector == PoolSelector.LEAST_LOADED:
            # O(log n) heap pop
            if self._pool_dirty:
                self._rebuild_pool_heap()

            pool_id = heapq.heappop(self._pool_heap)[0]
            heapq.heappush(self._pool_heap, (len(self._pools[pool_id]._workers), pool_id))

        return await self.execute_on_pool(pool_id, task)

    def _rebuild_pool_heap(self):
        """Rebuild heap from current pool states."""
        self._pool_heap = [
            (len(pool._workers), pool_id)
            for pool_id, pool in self._pools.items()
        ]
        heapq.heapify(self._pool_heap)
        self._pool_dirty.clear()
```

**Expected Improvement**: **O(log n)** vs O(n), critical for 100+ pools

---

## Moderate Performance Issues (Fix Soon)

### 8. **Circuit Breaker - No Request Coalescing**

**Location**: `/mahavishnu/core/circuit_breaker.py`

**Severity**: 🟡 MODERATE

**Issue**: Circuit breaker opens immediately on threshold but doesn't batch requests during semi-open state

**Impact**: Thundering herd problem when circuit recovers

**Optimization**: Add request batching during semi-open state

---

### 9. **Session Buddy Integration - No Connection Pool**

**Location**: `/mahavishnu/pools/memory_aggregator.py:58`

**Severity**: 🟡 MODERATE

**Current Performance**:
```python
self._mcp_client = httpx.AsyncClient(timeout=300.0)  # Single client
```

**Issue**: Only one HTTP connection, no pooling, no keepalive tuning

**Impact**: Connection overhead on every request (TCP handshake + TLS)

**Optimization**:
```python
self._mcp_client = httpx.AsyncClient(
    timeout=300.0,
    limits=httpx.Limits(
        max_connections=100,
        max_keepalive_connections=20,
        keepalive_expiry=30.0,
    ),
)
```

**Expected Improvement**: 20-50ms saved per request

---

### 10. **Workflow State - No Caching**

**Location**: `/mahavishnu/core/workflow_state.py:70-82`

**Severity**: 🟡 MODERATE

**Current Performance**:
```python
# Lines 72-82: Every get hits OpenSearch
async def get(self, workflow_id: str) -> dict | None:
    if self.opensearch and OPENSEARCH_AVAILABLE:
        try:
            response = await self.opensearch.get(index="mahavishnu_workflows", id=workflow_id)
            source = response.get("_source")
            return source if isinstance(source, dict) else None
```

**Issue**: No LRU cache for frequently accessed workflows

**Impact**: Repeated OpenSearch queries for same workflow_id

**Optimization**: Add `functools.lru_cache` or custom LRU with TTL

**Expected Improvement**: 10-50ms cache hits vs 100-200ms OpenSearch query

---

### 11. **Terminal Pool Lock Contention**

**Location**: `/mahavishnu/terminal/pool.py:59-79`

**Severity**: 🟡 MODERATE

**Current Performance**:
```python
# Lines 79-88: Single lock for all operations
async with self._lock:  # 🔒 Global lock
    if len(self._available_sessions) > 0:
        session_id = self._available_sessions.pop()
```

**Issue**: All session acquisition/deletion serialized

**Impact**: Under high load, sessions wait unnecessarily

**Optimization**: Use per-session locks or async queue without lock

**Expected Improvement**: Better concurrency under load

---

### 12. **Repository List - O(n²) Filter**

**Location**: `/mahavishnu/core/app.py:555-563`

**Severity**: 🟡 MODERATE

**Current Performance**:
```python
# Lines 556-563: Linear scan for filter
if tag:
    filtered_repos = [repo["path"] for repo in repos if tag in repo.get("tags", [])]
elif role:
    filtered_repos = [repo["path"] for repo in repos if repo.get("role") == role]
```

**Issue**: Rescans all repos every call

**Impact**: 100 repos × 1000 calls = 100,000 comparisons

**Optimization**: Build tag→repos and role→repos indexes on load

**Expected Improvement**: O(1) lookup vs O(n)

---

## Minor Optimizations (Nice to Have)

### 13. **Metrics Tracking - Unbounded List Growth**

**Location**: `/mahavishnu/pools/mahavishnu_pool.py:77`

**Severity**: 🟢 LOW

**Issue**: `self._task_durations: list[float] = []` grows without bound

**Impact**: Memory leak over long-running pools

**Optimization**: Use circular buffer or sliding window with max size

---

### 14. **String Concatenation in Logger**

**Location**: Multiple files

**Severity**: 🟢 LOW

**Issue**: `f"Pool {pool_id} spawned successfully (type: {pool_type})"` creates new string even if log level disabled

**Optimization**: Use lazy logging: `logger.info("Pool %s spawned", pool_id)`

**Expected Improvement**: Minor (micro-optimization)

---

### 15. **No Request Deduplication**

**Location**: Multiple adapters

**Severity**: 🟢 LOW

**Issue**: Identical requests to same repo execute independently

**Optimization**: Add request deduplication cache with short TTL

**Expected Improvement**: Avoid duplicate work in parallel workflows

---

## Network Communication Patterns

### Identified Issues

1. **No Retry Logic** (except circuit breaker)
   - Location: All HTTP calls
   - Impact: Transient failures cause permanent errors
   - Fix: Add exponential backoff retry

2. **No Request Timeouts** (except one case)
   - Location: Most async calls
   - Impact: Hung requests block forever
   - Fix: Add `asyncio.wait_for()` with timeout

3. **No Compression**
   - Location: Memory sync payloads
   - Impact: High bandwidth usage
   - Fix: Enable gzip compression for large payloads

---

## Database Operations

### OpenSearch Integration

**Current State**:
- **Connection**: Single client, no pool tuning
- **Indexing**: One-at-a-time, no bulk operations
- **Querying**: No query optimization, no result pagination
- **Fallback**: In-memory dict (unbounded growth)

**Issues**:
1. No bulk indexing (see issue #6)
2. No query result caching
3. No connection pool sizing
4. Fallback storage never cleaned up (memory leak)

**Optimizations**:
1. Implement bulk API for batch writes
2. Add query result cache with TTL
3. Configure connection pool size
4. Implement fallback cleanup/LRU eviction

---

## Lock Contention Analysis

### Identified Locks

| Location | Type | Contention Risk | Priority |
|----------|------|-----------------|----------|
| `terminal/pool.py:59` | `asyncio.Lock` | HIGH (session hot spot) | HIGH |
| `core/app.py:124` | `Semaphore` | MEDIUM (workflow limit) | MODERATE |
| `workers/manager.py:53` | `Semaphore` | MEDIUM (worker limit) | MODERATE |
| `message_bus.py:90` | `Queue` (implicit lock) | LOW (backpressure) | LOW |

**Recommendation**: Profile lock wait times under load using `asyncio.Lock.__repr__` or custom instrumentation

---

## Memory Usage Patterns

### Identified Memory Leaks

1. **Unbounded lists**:
   - `_task_durations` in pools
   - `local_states` in workflow state
   - Message queues (no max size enforced)

2. **No cleanup**:
   - Completed workflows kept forever
   - Old messages never pruned
   - Worker results never cleared

**Optimization**:
```python
# Implement cleanup tasks
async def cleanup_old_workflows(self, max_age_seconds=86400):
    """Remove workflows older than 1 day."""
    cutoff = time.time() - max_age_seconds
    for wid, state in list(self.local_states.items()):
        created = datetime.fromisoformat(state["created_at"]).timestamp()
        if created < cutoff:
            await self.delete(wid)
```

---

## Caching Strategies

### Missing Caching Opportunities

1. **Adapter health checks** - Cache for 30s
2. **Repository lists** - Cache until repos.yaml change
3. **Pool status** - Cache for 5s
4. **Workflow state** - Cache hot workflows in memory
5. **RBAC permissions** - Cache user permissions

**Recommended Cache**:
```python
from asyncio_atexit import register
from cachetools import TTLCache

class CachedRBACManager(RBACManager):
    def __init__(self, config):
        super().__init__(config)
        self._permission_cache = TTLCache(maxsize=1000, ttl=300)  # 5 min TTL

    async def check_permission(self, user_id, repo, permission):
        cache_key = (user_id, repo, permission)

        if cache_key in self._permission_cache:
            return self._permission_cache[cache_key]

        result = await super().check_permission(user_id, repo, permission)
        self._permission_cache[cache_key] = result
        return result
```

---

## Async Operation Efficiency

### Blocking Operations Identified

1. **File I/O**: No `aiofiles` usage (blocking file reads)
2. **YAML parsing**: Synchronous `yaml.safe_load()`
3. **Subprocess**: No async subprocess usage
4. **DNS resolution**: Blocking (no async DNS)

**Optimization**:
```python
# Use aiofiles for async file I/O
import aiofiles

async def _load_repos(self):
    async with aiofiles.open(self.repos_path) as f:
        content = await f.read()
        self.repos_config = yaml.safe_load(content)
```

---

## Performance Profiling Recommendations

### Instrumentation Points

1. **Pool spawning**: Track time from `spawn_pool()` to `RUNNING` status
2. **Task execution**: Track queue time + execute time
3. **Memory sync**: Track collection time + sync time
4. **Lock contention**: Track wait time per lock
5. **Network I/O**: Track request latency per endpoint

**Recommended Tools**:
```python
# Add to all critical functions
from functools import wraps
import time

def timed(func):
    @wraps(func)
    async def wrapper(*args, **kwargs):

## Performance Testing Plan

### Load Testing Scenarios

1. **Baseline**: 10 workflows across 5 repos, 5 workers
2. **Moderate**: 100 workflows across 20 repos, 20 workers
3. **High**: 1000 workflows across 50 repos, 50 workers
4. **Stress**: 10000 workflows across 100 repos, 100 workers

### Metrics to Track

- Workflow execution time (p50, p95, p99)
- Pool spawning time
- Memory sync latency
- Memory usage (RSS, heap)
- CPU utilization
- Network I/O
- Lock contention percentage
- Error rate

### Tools

```bash
# Install dependencies
pip install locust pytest-benchmark asyncio-atexit

# Run load test
locust -f load_tests.py --host http://localhost:3000 --users 100 --spawn-rate 10

# Profile specific function
python -m cProfile -o profile.stats your_script.py
```

## Conclusion

Mahavishnu has a **solid async foundation** but suffers from **critical performance bottlenecks** that will prevent production deployment at scale. The **N+1 network calls** in memory aggregation and **sequential pool operations** are the most severe issues, causing **10-50x slowdown** under load.

**Addressing the 2 CRITICAL and 5 HIGH issues will provide 5-50x performance improvements** across the board, making the system production-ready for moderate-scale deployments.

**Recommended next steps**:
1. Implement memory aggregation batching (Issue #1)
2. Implement concurrent pool collection (Issue #2)
3. Add OpenSearch log batching (Issue #6)
4. Remove duplicate semaphore (Issue #4)
5. Conduct load testing to validate improvements
6. Address moderate-priority issues iteratively

**Estimated effort**: 2-3 weeks for critical fixes, 1-2 months for full optimization.
