Description of problem:

The better performance was observed with the shard-size of 128MB.
Virt profile should have this attribute and so its set on the volume when the
volume is optimized for virt-profile

Version-Release number of selected component (if applicable):
-------------------------------------------------------------


How reproducible:
-----------------
NA

Steps to Reproduce:

Shard-size is set to 4MB

Expected results:
-----------------
shard-size should be set to 128MB so that perf improvement is observed

At the moment, performance tests are done with different values and the value
is yet to finalized based on the perf tests

When would the recommended shard-size can be provided so that the required
changes can be done?
