**Benchmark setup**

.. code-block:: python

    from pandas_vb_common import *
    
    df = DataFrame(np.random.randn(10000, 8), columns=list('abcdefgh'))
    df['foo'] = 'bar'
    
    row_labels = list(df.index[::10])[:900]
    col_labels = list(df.columns) * 100
    row_labels_all = list(df.index) * len(df.columns)
    col_labels_all = list(df.columns) * len(df.index)
    

**Benchmark statement**

.. code-block:: python

    df.lookup(row_labels_all, col_labels_all)
