Description Vidya Sakar 2012-08-21 13:13:54 UTC
Placeholder BZ for caching improvements we could do to improve virtual machine image store performance.

Comment 1 Amar Tumballi 2012-12-24 09:34:50 UTC
The below changes are been done:

* a gluster volume set <> group virt (which would disable not required xlators)
* better re-structuring of write-behind
* a way to handle O_DIRECT separately in write-behind and in client protocol.
* proper mtime update in distribute translator so the caching based on mtime in application is not invalidated.

All other caching is done by guest at the moment.
