Second this. CPU speed -> perf wasn't quite linear when I was testing that but was certainly highly improved with 2.4 and 2.6 and 3.0 GHz CPUs. >[...] > You use one disk solely for cache.

Use Linux LVM for mirroring the OS partition and logs partition, but no RAID/LVM on the cache dirs. -- -george william herbert george.herbert@xxxxxxxxx
