Nice thought, and something I hadn't checked, but unfortunately: # cat /sys/block/cciss\!c0d1/queue/scheduler noop anticipatory deadline [cfq] Changing it to deadline showed no appreciable difference in the results, but neither did any of the others. I may be missing something (or showing my ignorance), but should I be expecting to see a difference here given that this is hardware RAID? -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
