FYI, some folks have done some performance testing of Glance with Swift backends. It was determined that using SSL caused a dramatic performance degradation (roughly decreased the network I/O throughput by half, with a queuing behvaiour showing up on GET requests as well.) The solution was to disable zlib compression in SSL on the Glance API server box. There aren't a whole lot of easy ways to do this in OpenSSL 0.9.8, but you may find the discussion in this article interesting: http://journal.paul.querna.org/articles/2011/04/05/openssl-memory-use/ Cheers, jay _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
