So, we have a few options and one obvious thing to do. Obvious: increase the session lifetime in Apaches SSL engine. - will increase memory usage on the Apache FE's : unlikely to be an issue. I'll RT this now.
Move to a single IP single active server Apache FE. + immediate performance win + simple to understand - more load on that one machine Move to an LVS (or similar) single IP multiple servers Apache FE with shared SSL session cache + immediate performance win - more complexity Test out whether a shared SSL session cache with multiple ips helps + small incremental change - unknown whether it will help, and how much it will help (may reduce not eliminate round trips) We have a few big changes going on at the moment, and I'm concerned an LVS or similar deployment project will steal resources from getting those changes executed; so at the moment, my personal preference would be to go to a single active server, with failover in the event of failure/upgrades. -Rob _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
