5903 c/s real, 5903 c/s virtual

Intel(R) Pentium(R) 4 CPU 2.40GHz
4094 c/s real, 4355 c/s virtual

Pentium III (Coppermine)
2455 c/s real, 2455 c/s virtual

Can anyone provide any Athlon benchmarks?

I think that test isn't true, how It can know the speed to crack 2 or 8 
character password ?
In my cpu athlon xp 2500 barton (1833mhz) john -test show me 5308c/s 
(real and virtual) but in the reality it is cracking at 3500c/s 
(incremental:All after days)

The test is just a benchmark.  Your mileage may vary.  You should notice a
gradual decrease in speed as your incremental cracking works it way up to
more complex passwords.  I put together my own Perl-based system to
distribute cracking with a web interface for monitoring the progress.  Using
MRTG to graph the rate will show you a nice downward curve.  If you are
trying all characters you may want to reconsider based on the system from
which the password was taken.
