Performance tasks

Warning: This page is old. It is kept as an archive. Do not expect anything on it to be relevant to the current day.

This is just a notice board for various performance issues to be solved:

• wfGetSiteNotice should cache parsed text somewhere
• Use parsercache for ones with stubthreshold, I guess current link placeholders solve this.
• Forward-port cpu-time based profiler
• Hunt down and fix this query: query: SELECT page_id FROM `page` WHERE page_namespace='X' LIMIT N'
