http://bugzilla.kernel.org/show_bug.cgi?id=14830 --- Comment #16 from Michael Godfrey <godfrey@xxxxxxxxxxxxxxxx> 2010-01-29 06:37:55 --- I had a chance to try noop and deadline: With the amount of testing that I could do they seemed to behave about the same, and: 1. the task timeouts are gone. 2. sync, which used to take over 20 minutes is consistently about 10 minutes. I did retest by setting scheduler back to cfg and the sync time went back to 24 minutes. 3. I also tried 2 variations: 1. rsync from source to target: rsync machinea:/aaa bbb 2. rsync of an NFS-mounted filesystem to local filesystem. (i.e the rsync thought it was local: rsync aaa/ bbb, but aaa was NFS-mounted (NFS3). These two variation behaved just about identically. I have left the system set to deadline, as recommended. With this setting (and with noop) things like du seem quicker too. So, this is good, but 10 minutes for sync is still way too long. With these systems, I cannot compile debug kernels or stuff like that. They are in use for backup. Any other suggestions?
