Yup. About twice as fast for at least one dataset:
In [182]: import timeit
In [183]: t1 = timeit.Timer("s.split('\\x00', 1)[0]", "s='abc\\x00'*256")
In [184]: t2 = timeit.Timer("s[:s.index('\\x00')]", "s='abc\\x00'*256")
In [192]: t1.repeat(3, 100000)
Out[192]: [0.68063879013061523, 0.67146611213684082, 0.66347002983093262]
In [193]: t2.repeat(3, 100000)
Out[193]: [0.35819387435913086, 0.35968899726867676, 0.37595295906066895]
