$ ./python.exe -m timeit "b'x'.decode('latin1')" 100000 loops, best of 3: 2.57 usec per loop $ ./python.exe -m timeit "b'x'.decode('latin-1')" 1000000 loops, best of 3: 0.336 usec per loop The reason for this behavior is that 'latin-1' is short-circuited in C code while 'latin1' has to be looked up in aliases.py. Attached patch fixes this issue.
