[Gluster-users] Increase or performance tune READ perf for glusterfs distributed volume

[Karan Sandha]

Hi Deepak,

Are you reading a small file data-set or large files data-set and 
secondly, volume is mounted using which protocol?

for small files data-set :-

**

*gluster volume set *vol-name* cluster.lookup-optimize on (default=off)*

*

gluster volume set *vol-name* server.event-threads 4 (default=2)

gluster volume set *vol-name* client.event-threads 4 *(default=2)*

*

and do a re-balance on the volume and then check the performance, we 
generally see a performance bump up when we turn these parameter on.

Thanks & regards

Karan Sandha
