Thats a significant speed increase

jtnumberfive · #2 (**permalink**) 07-14-2005

Can someone help me intrepret these results? I have another computer that I have been comparing them with that is significantly slower- p2 400 mhz with 160 mb ram- having trouble determining which is better

Dell optiplex with 768mb ram and fedore core 3 linux kernel 2.6.9
