## 8. Performance and Optimization

### 8.1 Profiling System

**BioQL Profiler:**

```python
from bioql.profiler import Profiler

profiler = Profiler()

# Profile quantum execution
result = profiler.profile_quantum(
    "dock aspirin to COX-1",
    api_key="bioql_...",
    backend="ibm_torino",
    shots=1024
)

# Get report
report = profiler.get_report()

print(report)
# {
#   "total_time": 45.3,              # seconds
#   "parsing_time": 0.5,
#   "compilation_time": 2.1,
#   "backend_queue_time": 30.0,
#   "execution_time": 10.5,
#   "postprocessing_time": 2.2,
#   "overhead_percent": 4.8,         # <5% target
#   "gate_count": 1024,
#   "circuit_depth": 87,
#   "qubits_used": 12
# }
```

**Dashboard Generation:**

```python
# Generate interactive HTML dashboard
profiler.generate_dashboard(
    output_file="bioql_profile.html"
)

# Includes:
# - Time breakdown charts (Plotly)
# - Gate count histograms
# - Resource utilization
# - Cost analysis
# - Circuit visualizations
```

### 8.2 Circuit Optimization

**Optimization Results:**

```python
from bioql.optimizer import optimize_circuit

original_circuit = create_circuit(...)

optimized = optimize_circuit(
    original_circuit,
    backend="ibm_torino",
    optimization_level=3
)

print(f"Gate reduction: {optimized.gate_reduction_percent}%")  # 35%
print(f"Depth reduction: {optimized.depth_reduction_percent}%")  # 35%
print(f"Fidelity improvement: {optimized.fidelity_gain}%")  # 20-40%
```

**Optimization Techniques:**

1. **Template Matching**: Replace gate sequences with equivalents
2. **Peephole Optimization**: Local gate pattern optimization
3. **Commutation Analysis**: Reorder gates for parallelism
4. **SWAP Reduction**: Minimize routing overhead
5. **Gate Decomposition**: Efficient native gate conversion

### 8.3 Caching System

**Smart Caching:**

```python
from bioql.cache import enable_cache

enable_cache(
    max_size_mb=1000,           # 1GB cache
    ttl_seconds=86400,          # 24 hours
    strategy="lru"              # Least Recently Used
)

# Cached items:
# - Compiled circuits
# - Molecular Hamiltonians
# - Quantum results (by circuit hash)
# - Backend calibration data
```

**Performance Gains:**

- **24x speedup** for repeated circuits
- **70% cache hit rate** in production
- Automatic invalidation on backend changes
- Circuit hash-based deduplication

### 8.4 Job Batching

**Intelligent Batching:**

```python
from bioql.batcher import batch_jobs

jobs = [
    {"circuit": circuit1, "shots": 1024},
    {"circuit": circuit2, "shots": 1024},
    {"circuit": circuit3, "shots": 1024}
]

results = batch_jobs(
    jobs,
    backend="ibm_torino",
    max_batch_size=300          # Backend limit
)

# Benefits:
# - 18-30% cost savings (fewer job submissions)
# - Reduced queue time
# - Automatic job splitting
# - Failure recovery per sub-job
```
