1. 64MB machines beat 192MB and 240MB machies. 2. On 64 MB machine I tested on 5400rpm drive and still much faster than athlon machine. 3. On sis machine I am using a separete ati agp card not the built in one and as a result i am using all memory. You would expect AMD machines to be at least slightly faster because cpu speed ratio are about 2 or bigger. You might not expect linear scaling but at least faster you know. Also as I said kernel compilation time scales almost linearly with cpu speed On Fri, Apr 26, 2002 at 09:49:31AM -0400, P.J.
