[Gluster-users] Slow write times to gluster disk

[Pat Haley]

Hi,

We were recently revisiting our problems with the slowness of gluster 
writes 
(http://lists.gluster.org/pipermail/gluster-users/2017-April/030529.html). 
Specifically we were testing the suggestions in a recent post 
(http://lists.gluster.org/pipermail/gluster-users/2018-March/033699.html). 
The first two suggestions (specifying a negative-timeout in the mount 
settings or adding rpc-auth-allow-insecure to glusterd.vol) did not 
improve our performance, while setting "disperse.eager-lock off" 
provided a tiny (5%) speed-up.

Some of the various tests we have tried earlier can be seen in the links 
below.  Do any of the above observations suggest what we could try next 
to either improve the speed or debug the issue?  Thanks
