<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>We have two nodes which are serving PHP webpages with PHP5-FPM. Both Nodes are configured with drbd in dual primary mode.</div>
<div>In our tests, if one of these two nodes get 10-20 Pagerefresh's at the same time, the CPU are 100% in use.</div>
<div>For these 10-20 Pagerequests the server are 1.5 minutes busy.</div>
<div> </div>
<div>Without OCFS (harddrive is formatted with ext4) for the same 10-20 requests, it tooks only 0.1 Seconds to complete.</div>
<div>We only see a long running PHP Process which get timeouted sometime with '30 seconds exceeded for including a file' . We tried mounting the ocfs2 device with 'noatime, nodiratime, data=writeback', but it didn't helped.</div>
<div> </div>
<div>does someone has a tip for us ?</div>
<div>(If we use ocfs2 with icsci, there are no changes)</div>
<div> </div>
<div>thanks a lot!</div></div></body></html>
