Thread:Project:Support desk/Very slow MW website, possibly due to database/reply (11)

Hi pal,

Tweaking mysql config and giving innodb buffer pool more memory seemed to have done the trick. The site worked fairly good for a couple of days. But again, with no apparent reason, suddenly the website came back to its usual behaviour and now again it gets stuck after every 20 minutes or so.

Apache status shows that there are lots of "Sending reply" connections with code "W"... and eventually apache chokes and dies. I am using very plain Monobook Skin with minimum number of extensions (all extensions are common ones and stable). index.php is the culprit when I see the apache status. Most of the connections with "W" are stuck with index.php

But I wonder, why not all the MW websites get choked if there is something wrong with MW code? We all use the same code downloaded from MW website.

Anymore suggestions that you can spare in my quest to find a solution?

PS: I am upgrading my server and getting an extra GB of RAM
