Ok, so its hard to say just from this. Some general things that may or may not apply:
- try disabling all extensions just to elliminate faulty extension as a
cause.
- enable profiling (if possible. Probably requires installing xhprof) to
determine what mediawiki is spending all its time doing. This would be the most useful thing to figure out what is going on.
- if using sqlite, switch to mariadb (sqlite has poor concurrency)
Some general performance tips:
- ensure that caching is enabled. On IIS you probably want to set up
XCache. Otherwise use apcu. Once apcu or xcache is set up, make sure wgMainCacheType = CACHE_ACCEL; *although windows is supported, mediawiki is definitely better tested on linux.

We're having issues with a MW installation that gets very slow when multiple users are logged in simultaneously. After a while the wiki
becomes
unresponsive and in some cases gives HTTP error 500. This has occurred
with
as few as three users logged in at once.
The wiki was installed on a Windows server 2016-server, following this guide:
https://www.mediawiki.org/wiki/Manual:Installing_ MediaWiki_on_Windows_Server_2016 .
My first thought was that there was too little server resources, but when
I
looked at the task manager, CPU was fairly consistently between 5 and 25% (there were a few spikes) and the RAM was steady at around 50%. MW
version
is 1.30.0.
I have turned on logging (following these instructions: https://www.mediawiki.org/wiki/Manual:How_to_debug#Logging), but I can't find any obvious cause for this behaviour. I have compiled a list of messages that looks suspicious here:
https://phabricator.wikimedia.org/P6814.
I didn't want to post the whole log since the logging instructions had security warnings about this.
Any help with how to proceed finding the cause for this and fixing it
would
be much appreciated.
All the best,
