The hdparm optimizations, the CFQ scheduler and maybe low latency desktop in the kernel are the best way to make your desktop useable under heavy disk usage.These are my hdparm settings: /dev/hda: multcount = 16 (on) IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 26310/16/63, sectors = 26520480, start = 0 cat /sys/block/hda/queue/scheduler noop [cfq] Linux c-68-85-77-239 2.6.20-gentoo #4 PREEMPT Tue Feb 6 17:03:56 EST 2007 i686 AMD Athlon(tm) XP 2000+ AuthenticAMD GNU/Linux -- gentoo-user@gentoo.org mailing list
