The current gluster-swift integration code has references to the use of memcache, but there was no facility to hook it up, and the code makes an extra stat() system call for the memcache objects that is not necessary since memcache is not in use. This is yet another drag on the performance of container HEAD and GET requests.
Assigning the bug to myself as I have already sent the patch.
Comment #1 from Junaid says there is already a fix. is this in G4S?
