Caching improvements for virtual machine image store
Last modified: 2013-12-08 20:33:05 EST
Placeholder BZ for caching improvements we could do to improve virtual machine image store performance.
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.
