So , You dont think that any configuration changes like increasing the number of volumes or anything else will help in reducing the I/O wait time ?

No, because that won't change the number of heads that are present to service the IO requests, nor to segregate requests effectively. Your primary goals should be to reduce IO (investigate using LVM backed VMs instead of file-backed)
[Jatin] Sure , I have no idea about LVM so i will do my learning on it. Thanks for pointing to it.
or to increase hardware resources (possibly a larger number of smaller disks if SSDs are not in budget).
[Jatin] This is also one option that i can try for sure since usage of disks instead of SSDs certainly falls within my budget.
