[Gluster-users] client is terrible with large amount of small files
Hi bturner,
I am getting below error while adding server.event
gluster v set integvol server.event-threads 3
volume set: failed: option : server.event-threads does not exist
Did you mean server.gid-timeout or ...manage-gids?
Glusterfs version has been upgraded to 3.6.3
Also os kernel upgraded to 6.6 kernel
Yes two brick are running in KVM and one is physical machine and we are not
using thinp.
Regards
G.J

Upgrade to 3.6.3 and set client.event-threads and server.event-threads to at
least 4. Here is a guide on tuning MT epoll:

Are your bricks on LVM? Are you using thinp? If so update to the latest kernel
as thinp perf was really bad in 6.5 and early 6.6 kernels.
