Manual talk:Performance tuning

disable mbstring.func-overload ?
it is recommended to disable mbstring.func-overload. How can I do that? Is "php_admin_value mbstring.func-overload 0" fine? --Subfader (talk) 20:24, 27 March 2012 (UTC)

Unnecessary extensions
What about disabling unnecessary extensions? Are there some extensions listed at wikipedia:Special:Version that use up a lot of resources, that most wikis wouldn't need? Leucosticte (talk) 11:20, 16 December 2013 (UTC)

Compress JavaScript
I notice that there are wikis around which make me download a lot of uncompressed JavaScript... we should really document that here. --Nemo 22:47, 19 November 2014 (UTC)

Performance tuning with LinkTitlesParseOnRender=true
We have huge performance problems with Linktitles since we want no hard coded links on our wikipages and we have logged in users only. As far as I understood, SQUID can help us only with anonymous users. Am I right? I found no other option to precache pages for logged in users... :/ My Idea: Is there a way to deliver the anonymous user cache to a logged in user and only when pressing the "Edit" button it will consider that this user is logged in? Any other ideas? --> Thanks in advnace
