Thread:Project:Support desk/Slow MediaWiki due to Nginx reinstall?

Hello,

I wanted to upgrade from nginx 1.4.1 to 1.4.2. Something went wrong and nginx does not want to start anymore. So I reinstalled all nginx packages. After a day the users of my Wiki said that the wiki is horribly slow (about 5-9 seconds / pageload). I could not find any mysql slow querys, or something. Only php5-fpm says now that all child processes are in use (pm.max_children = 5). Now i have to set pm.max_children = 60 to avoid these messages. Today I installed nginx 1.4.2 correctly but still the Wiki is slow. On the same server Wordpress and WBB are running blazing fast, only MediaWiki got slower. I am using APC with $wgMainCacheType = CACHE_ACCEL; so i thought maybe with APC is something wrong, so I reinstalled APC without effect.

MediaWiki is using APC: CACHES: APCBagOStuff[main] APCBagOStuff[message] APCBagOStuff[parser] On every query: "MessageCache::load: Loading de... got from global cache" I cant see anything suspicious in MediaWikis log except: "Loaded preprocessor XML from memcached" I havent configured memcached in LocalSettings and memcached isnt even running (but installed)...

The load of my server is horrible high. (was ~1, now is [2.5,4])

Specs: MediaWiki: 1.20.6, 5.4.9-4ubuntu2.2 (fpm-fcgi), 10.0.3-MariaDB-1~raring-log, nginx/1.4.2/1.4.1

Thanks in advance.
