Profiling

14:38 TimStarling: ok, here's how to do the profiling
14:38 TimStarling: I'm doing it now if you want to watch :)
14:39 TimStarling: you log into suda, and run a "truncate table profiling" query on en
14:39 TimStarling: then (usually in a different window) you open CommonSettings.php
14:40 TimStarling: you search for profiling
14:40 TimStarling: you find a commented-out section
14:40 TimStarling: uncomment it
14:41 TimStarling: like that
14:41 TimStarling: the sample rate is 50 by default, that means it profiles 1 in every 50 requests
14:41 TimStarling: it will take a while at this rate to build up some decent data
14:42 TimStarling: run: sql enwiki -vvv < ~tstarling/sql/profiling.sql
14:43 TimStarling: make a local copy of that SQL and adjust the screen width if you desire

14:45 TimStarling: anyway, once you have enough data, you comment out the section in
-               CommonSettings.php again
14:46 TimStarling: then run the SQL again, copy the data to a subpage of m:Profiling, and analyse
-               the results
