Can anyone provide any Athlon benchmarks?

Thats on an Athlon XP 1800+, which is running at ~1500MHz.

When I'm cracking passwords that I suspect of being abnormally hard to
crack, I do my best to tweak my John run(s) accordingly.  i.e., on
solaris I'll make the max password length 8 and the minimum something
like, oh, 6 or whatever local restrictions might be in place.  I've also
had good results running 3 incremental cracks at once (on the same
machine if 4 processors are available, otherwise on 3 different
machines), using the "All", "Alpha" and "Digits" incremental cracks.

17 days is quite a long time, but keep going.
