**Benchmark setup**

.. code-block:: python

    from pandas_vb_common import *
    
    rng = DateRange('1/1/2000', periods=10000, offset=datetools.Minute())
    
    ts = Series(np.random.randn(len(rng)), index=rng)
    ts2 = ts[::2]
    ts3 = ts2.reindex(ts.index)
    
    def pad():
        try:
            ts2.reindex(ts.index, method='pad')
        except:
            ts2.reindex(ts.index, fillMethod='pad')
    def backfill():
        try:
            ts2.reindex(ts.index, method='backfill')
        except:
            ts2.reindex(ts.index, fillMethod='backfill')
    

**Benchmark statement**

.. code-block:: python

    ts3.fillna(method='backfill')
