We've not seen this behavior in our internal tests (We have done quite a significant amount of testing on this to ascertain performance impact). We need to investigate this. Can you file a bug on this providing following information: * log files of client and brick process * test-case to reproduce the issue. * Test environment (OS, volume profile info etc). regards, Raghavendra > > Cheers, > > On Mon, Jan 29, 2018 at 9:26 AM Raghavendra Gowdappa < rgowdapp@xxxxxxxxxx > > wrote: > > > > > ----- Original Message ----- > > From: "Pranith Kumar Karampuri" < pkarampu@xxxxxxxxxx > > > To: "Alan Orth" < alan.orth@xxxxxxxxx > > > Cc: "gluster-users" < gluster-users@xxxxxxxxxxx > > > Sent: Saturday, January 27, 2018 7:31:30 AM > > Subject: Re: parallel-readdir is not recognized in > > GlusterFS 3.12.4 > > > > Adding devs who work on it > > > > On 23 Jan 2018 10:40 pm, "Alan Orth" < alan.orth@xxxxxxxxx > wrote: > > > > > > > > Hello, > > > > I saw that parallel-readdir was an experimental feature in GlusterFS > > version > > 3.10.0, became stable in version 3.11.0, and is now recommended for small > > file workloads in the Red Hat Gluster Storage Server documentation[2].
