Description SATHEESARAN 2018-08-21 10:54:14 UTC 
Description of problem:
------------------------
The option performance.client-io-threads, which has been unavailable as a tuning option for replicated volumes in recent releases, is available in RHGS 3.3.1-async and RHGS 3.4. RHHI can benefit by adding it to the group virt profile, along with a few others. The following is the list of suggested additions to group virt:

performance.client-io-threads on
client.event-threads 4
server.event-threads 4

In addition, "cluster.choose-local false" is beneficial, and is already covered in bz #1568297.

In most random I/O tests on flash, the fuse thread is currently seen to be the bottleneck. client-io-threads, along with the other options, helps push IOPS far beyond what RHHI can currently provide.
