Some more testing: Patch 308 time tar -cvf /mnt/glusterfs/test/test.tbz 0 1 2 3 real 6m47.947s user 0m0.180s sys 0m1.220s Patch 313 time tar -cvf /mnt/glusterfs/test/test.tbz 0 1 2 3 real 9m21.909s user 0m0.160s sys 0m1.470s Patch 313 also used 50% more memory. This leads me to suspect the problem is in writebehind or posix-locks Harris ----- Original Message ----- From: "Harris Landgarten" <harrisl@xxxxxxxxxxxxx> To: "gluster-devel" <gluster-devel@xxxxxxxxxx> Sent: Saturday, July 14, 2007 2:23:20 PM (GMT-0500) America/New_York Subject: Slowness and segfault with 313 Last weekend with 299 a full Zimbra backup completed in 27 minutes.
