That's a nice theory. But when I use CPU intensive programs like gzip on SPARC and Intel machines I find that I get about the same amount of work done MHz for MHz on Intel and SPARC. In my tests a P2 @ 400MHz is faster than a SPARC at 250MHz. BTW I don't really care what programs like SPEC-CPU say about CPU performance. Programs that I run and which use lots of CPU time such as gzip, and clfmerge run faster on Intel. > > The symptoms (for the third time) are that the screen goes entirely blank > > but then anything which is re-drawn (for any reason) displays fine. > > If you didn't change your X server or libs, then check your BIOS > settings and make sure you're not using something that would lag > refresh.

I did install a new X server (ver 4.0) at the same time. But the problem also occurs in console mode with no X server running. -- http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/projects.html Projects I am working on http://www.coker.com.au/~russell/ My home page
