Jens Axboe 206dc69b31 [BLOCK] cfq-iosched: seek and async performance fixes ... Detect whether a given process is seeky and if so disable (mostly) the idle window if it is. We still allow just a little idle time, just enough to allow that process to submit a new request. That is needed to maintain fairness across priority groups. In some cases, we could setup several async queues. This is not optimal from a performance POV, since we want all async io in one queue to perform good sorting on it. It also impacted sync queues, as async io got too much slice time. Signed-off-by: Jens Axboe <axboe@suse.de>		2006-03-28 13:03:44 +02:00
