Re: [Mediawiki-l] [Upgrade 1.9.3 -> 1.11.0] Slow performance

Hi all, I just upgraded my mediawiki installation from version 1.9.3 to 1.11.0. The upgrade went smoothly (including the maintenance/update.php part) but now page delivery from the server is incredibly slow (about 40s for each page). For testing purposes I also did a fresh install of version 1.11.0 using a copy of the original database. This one is running smoothly (2s per page) although the LocalSettings.php are identical (except the necessary differences; checked with diff). I turned on profiling and it seems that the server is waiting for a memcached-server (see below): -------------------------------------------------------------------------------------------------------------------------- Start request GET /wiki/index.php5/Hauptseite Accept: */* Referer: http://XXXXX/er_page/ Accept-Language: de Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727) Host: dephd0080.rockwellcollins.com Connection: Keep-Alive Cookie: wikidbUserID=fDSY6tzj5mRmRSbScc7kkfb5MVNtrdUpbtn-YKamQeI.; wikidbUserName=BU6md5v7QoBjaPWgjiDFKQ6zUFA6qcnb5kDAN4bLZDo.; wikidbToken=WCECG_8rs-DpCfE9biU2YMIQQNwjsrbzvdiSwJTLAaFHDMZ-wNU4NaARwKVGXgY-; wikidb_session=Ly7ZvAQ1kMeToIurVQUAbzTyN6aG7WmzRCC7RkbP7VY9AztrT_pPCzTpmDsuTMwQ Main cache: FakeMemCachedClient Message cache: MediaWikiBagOStuff Parser cache: MediaWikiBagOStuff Unstubbing $wgParser on call of $wgParser->setHook from efSubpageList Fully initialised Unstubbing $wgContLang on call of $wgContLang->checkTitleEncoding from WebRequest::getGPCVal Language::loadLocalisation(): got localisation for de from source Language::loadLocalisation(): got localisation for en from source Unstubbing $wgUser on call of $wgUser->isAllowed from Title::userCanRead Cache miss for user 14 Unstubbing $wgLoadBalancer on call of $wgLoadBalancer->getConnection from wfGetDB Logged in from session Unstubbing $wgOut on call of $wgOut->setSquidMaxage from MediaWiki::performAction Unstubbing $wgLang on call of $wgLang->getCode from User::getPageRenderingHash OutputPage::checkLastModified: client did not send If-Modified-Since header Article::tryFileCache(): not cacheable Article::view using parser cache: yes Trying parser cache wikidb:pcache:idhash:1-0!1!0!!de!2 Parser cache miss.
