[00:06:21] <mszabo>	 yea that one

[20:13:07] <Krinkle>	 rendering action=history on officewiki is... slow.
[20:13:50] <Reedy>	 Any particular page(s)?
[20:24:02] <Krinkle>	 the one I profiled is [[Contact list]] after the 2nd page
[20:24:44] <Krinkle>	 the main one that stands out a lot (after clicking "Left Heavy" in Excimer UI/Speedscope) is Thanks hooks
[20:31:05] <Krinkle>	 Clicking on Sandwhich, the top one is Database select, at 440ms, divided between: 1) Thanks/canReceiveThanks/User::isSystemUser/User::loadFromDatabase, 2) Thanks/canReceiveThanks/User::isBot/UserGroupManager, 3) Thanks/generateThankElement/GenderCache, 4) Disambiguator/onGetLinkColors/Lookup
[20:31:46] <Krinkle>	 but more generally it's just doing a ton of repeated formatting etc, I recall TimStarling doing refactoring on something like this a year or so go, but that must've been something different.
[20:31:51] <Krinkle>	 ah that was Contributions I think, not History.
