The box is an IBM Thinkpad with 256MB of RAM and a 900MHz P-III cpu. No-name IDE disk (believe me, I made sure everything there was expendable), workload being dbench 16 on reiserfs over loop with a 256MB reiserfs loop file. I'm actually not entirely sure what the filesizes were as dbench didn't report that.
