I have a PIII 700 MHz Coppermine processor with 256 KB Full speed Advanced
Transfer Cache (ATC). Isn't this supposed to perform better that 512K
half-speed cache?? Anywahy, Mrinal is running on a Celeron... think of the
cache factor for that??

Oddly enough, even if I run two simultaneous clients (from separate
directories of course) I get the same 16 hrs per work unit !!!

Now I'm  even more surprised!! Anyone with an explanation??
