--- Comment #9 from Arthy Loganathan <aloganat at redhat.com> ---
I have executed the test with md-cache setting configured on the volume and
with 2 clients, I am still seeing the issues.

1) When there are ~40000 files, ls gets hung for more than two hours.

2) File creation(each file 100k size) is very slow when doing ls on mountpoint
from other client.

3) ls takes more time to list files even after stopping the file creation on
one client.
