I meant to send this yesterday.. oops The hard time is now 11 seconds, and we saw 800 timeouts (about 0.02% of requests)
There are about 20 page ids we need to improve before we can drop to 10 seconds : there are another 1000 page renders falling between 10 and 11 seconds at the moment. That means we could be dropping the timeout to 10 seconds as early as the start of April... as usual I'll be reevaluating as we go. This is pretty exciting to me: we've come an incredibly long way since we started systematically measuring and focusing on render times [as the first plank in becoming fast overall] : thats a 9 second drop in 9 months. I credit our achievement to the following things: - you guys - some small coding rule changes (like permitting cached property on model objects, and query count tests) - the restructure allowing folk the time to dig into a timeout problem over several days without being pressured by feature work (and vice verca, allowing features to be made fast without interrupts for day-to-day issues) - a willingness from our user base for us to make engineering tradeoffs (such as moving the safety net of the hard timeout every time we've got room to improve without causing a mass increase in the timeouts, removing features that are underperforming or of little benefit but high cst) I've been casually polling folk as we've gone through the process so far, and in the last couple of weeks a very interesting change has occured: rather than hearing 'gee LP is slow, its great you are improving it, I've notice some improvements already', I'm now hearing 'you know, I haven't been pissed off by LP being slow recently.' That might come across as faint praise, but its really significant: *** We've moved out of the zomg slow bucket and into the just-another-website bucket *** Now, we have 2 more seconds to drop our hard timeout by, to reach Francis' challenge of 9 seconds for the next epic : I'm sure we'll manage that without any difficulty. -woo- -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
