Am I the only person using Gluster suffering from very slow directory access? It's so seriously bad that it almost makes Gluster unusable. Using NFS instead of the Fuse client masks the problem as long as the directories are cached but it's still hellishly slow when you first access them. Has there been any progress at all fixing this bug? https://bugzilla.redhat.com/show_bug.cgi?id=1067256 Cheers,

[Gluster-users] Horrendously slow directory access
I am seeing something perhaps similar. 3.4.2-1, 2 servers, each with 1 brick, replicated. A du of a local (ZFS) directory tree of 297834 files and 525GB takes about 17 minutes. A du of the gluster copy is still not finished after 22 hours. Network activity has been about 5-6KB/sec until (I gather) du hit a directory with 22450 files, when activity jumped to 300KB/sec (200 packets/sec) for about 15-20 minutes. If I assume that the spike came from scanning the two largest directories, that looks like about 8K of traffic per file, and about 5 packets. A 3.3.2 gluster installation that we are trying to retire is not afflicted this way. James Bellinger> > Am I the only person using Gluster suffering from very slow directory > access?
