Hmm - that appears to be negligible if not within the bounds of
statistical error. However, you're right - a small bump in speed.
A Quick Aside:
Benchmarking the diff routines on my app (Changes - http://changesapp.com/)
showed a 10-15% performance increase going from 32-bit i386 to 64-
bit x86-64. I'm pretty sure that this is due to vast architectural
improvements in x86-64 vs. i386 (more GPRs, etc.). Unfortunately, due
to bugs in 64-bit Cocoa, I can't ship a 64-bit binary. The results of
benchmarking 32-bit ppc to 64-bit ppc64 showed a negligible/non-
existent improvement. This app was implemented using C/C++ and ObjC.
