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

 * puppet/modules/role/manifests/simple_performant.pp
 * puppet/modules/role/manifests/simple_miser.pp files
 * if you install puppet, you can make them all at once with a single command.

mod_disk_cache instructions
This page is from 2011, seems to be about 1.16, and says you need to hack a core file to make it work properly. It also gives an inaccurate description of s-maxage (s = shared, not stale). Would be nice if a more accurate and up to date instruction page could be provided. 9cfilorux (talk) 19:24, 13 June 2019 (UTC)

default of wgMainCacheType
The default of $wgMainCacheType in MediaWiki 1.31.5 is CACHE_ACCEL that makes the section Manual:Performance_tuning unnecessary.

 * The default (github.com/wikimedia/mediawiki/blob/REL1_35/includes/DefaultSettings.php#L2462) is CACHE_NONE. CACHE_ACCEL is set by the installer if a cache is available during installation. If no cache was available, the installer sets this value to CACHE_NONE. AdamMillerchip (talk) 03:47, 3 February 2021 (UTC)

PHP object caching
Both APCu and Opcache are mentioned as being the recommended PHP object caches, so which one is truly the recommended one, or are there situations that can favor one over the other? Voidwarped (talk) 14:55, 21 April 2020 (UTC)
