I found that using the "noop" I/O scheduler as well as doing "sync" to flush out file system buffers helped speed up performance. You can do it on-the-fly w/o rebooting using the a command like: echo 'noop' > /sys/block/sdb/queue/scheduler OR you can set it in your boot grub boot menu as a kernel option: ======================================= I found that by appending the string elevator=as to the end of the kernel parameters in /boot/grub/menu.lst, you can enable anticipatory I/O scheduling. The strings elevator=deadline and elevator=noop can be used as well, though I'm not so sure about their effects.
