[00:00:17] <Krinkle>	 contributions fairly rare, and Recentchanges only one entry point that is user/page agnostic. action=history is everywhere.
[00:00:24] <Krinkle>	 althoguh... that's CDN cachable at least
[00:00:40] <Krinkle>	 that one should be memcacheable centrally if not already
[00:00:48] <Krinkle>	 assuming it is the same on all pages, right?
[00:01:36] <Krinkle>	 hm.. well, despite action=history being purged. devetools tells me it is not cdn cachable today
[00:02:14] <Krinkle>	 well, not publicly, let me check on mw-web directly
[00:03:27] <Krinkle>	 It seems https://wikitech.wikimedia.org/wiki/Debugging_in_production#Debugging_a_web_request / https://wikitech.wikimedia.org/wiki/MediaWiki_Engineering/Guides/Measure_backend_performance#Benchmarking_and_load_testing_in_production are not yet satisfied by mwdebug's sunsetting.
[00:07:18] <Krinkle>	 There's no curl in mwexpshell :) https://phabricator.wikimedia.org/P84273
[00:07:54] <Krinkle>	 but `krinkle@wikikube-worker-exp1001:~$ curl -I --connect-to ::$HOSTNAME:4456` seems to work
[00:09:01] <Krinkle>	 krinkle@wikikube-worker-exp1001:~$ curl -I --connect-to ::$HOSTNAME:4456 'https://en.wikipedia.org/w/index.php?title=Banana&action=history'

[00:09:12] <Krinkle>	 OK, that's still fine then at least, but yeah long tail, worth optimizing
