Could you run hashcash -sv and send that? (-s is fast but not that
accurate -sv gives you the full slow benchmark).
http://www.hashcash.org/benchmark/
seem to have acquired a 600Mhz P3 sample: 0.96Mh/s (Mh = 20bits) which
is 1.1s for 20 bits.
Can't remember where from but interesting to cross check with your P3.
