I tried compiling both with and without preempt. In both cases 2.6.11 was very very slow. As soon as I tried 2.6.12rc3 with the same .config file the system became much more responsive and much faster in general too. For example with 2.6.11 copying a 600MB file from one location on the harddrive to somewhere else on the same drive resulted in transfer speeds of roughly 1-2MB/s with 2.6.12 the same file was being transfered at 10 times that! The only issue I had with 2.6.12rc3 was stability but a little tweaking of my .config file seems to have fixed that. Grahame
