When we upgraded to P200MMX from P90 I run a test with about ten programs snd the average speed-increase was 2,4x. I also checked the difference with 256k cache and 512k the difference was just over 1% (from 0-3%). We are just now testing P2-450, Celeron450 and AMD to find out the speed improvement vs P200MMX. Several programs are about twice as fast but Nimzo98 is nearly 3 times faster! (P2-450) Bertil >Enrique > >>Inc.
