Before we go about doing this, it would be better to run tests with performance translators enabled & disabled in our performance setup. Only when we have the data let us bring about this change. I agree, 3.3 would be a good release to make this decision. I think we should do it anyways ASAP, as I see that in many cases NFS sends open with GF_OPEN_NOWB flag (on wbflags arg), which makes the translator a pass through. So don't see much use on this anyways. Avati/Vijay, any thoughts on this? Actually with anon-fd changes the writebehind is not getting disabled for writes anymore. I think this was the reason we saw write performance drop (with perf xlators 'dd' gave 75 MBps and without perf xlators it gave 100MBps on gige). Also write-behind was never getting used before anon-fd changes. CHANGE: http://review.gluster.com/2883 (volgen: by default don't include performance xlators in nfs volfile) merged in master by Anand Avati (avati) Verified with 3.3.0qa42. |
