Hi Pratik,
What's the version of gluster you're running?
Also, what would help is the volume profile output. Here's what you should do to capture it:
# gluster volume profile <volname> start
# run_your_workload
# gluster volume profile <volname> info > brick-profile.out
And attach brick-profile.out here.

Offhand I do not see any issue with the configuration. But I think for
VM images store, using gfapi may give better performance than compared
to fuse. CC'in Kritika and Gobinda who have been working on this
use-case and may be able to guide you.
Thanks,
Soumya

It would be great if you can suggest me whether I should stick with glusterfs or move to any other technology. Currently I am using Glusterfs with fuse on CentOS for Storing images of Virtual Machine in CloudStack Setup. Majority of workload is of SQL Server & MariaDB database server, and some Web Servers. The issue is of slow booting and slow UI response of VMs and also lot of time outs in SQL server database even on small databases. I have dedicated 10G network for storage in my setup.
