Thanks! Sounds good. Um, how do I select a scheduler? :-)
RTFM: /usr/src/linux/Documentation/block/switching-sched.txt and /usr/src/linux/Documentation/kernel-parameters.txt (for elevator=)
# cat /sys/block/sd?/queue/scheduler # echo cfq > /sys/block/sdX/queue/scheduler
E.g. I have:
# cat /sys/block/sd?/queue/scheduler [noop] deadline cfq noop deadline [cfq]
15.1 switched to multiqueue framework, none of those schedulers is present here.
That's why I used 'cat /sys/block/sd?/queue/scheduler' to have people have a look at the available schedulers (which depends on the precise kernel-config) and then use whatever they deem (or find out through experiments works) best. And I pointed to the actual documentation. -dnh -- /* After several hours of tedious analysis, the following hash * function won.
