Recently I tried upgrading to mediawiki 1.19 on a shared server (hosted by Dreamhost).
After upgrading to 1.19, my site was sooooooooo slow that it was barely operable. Pages
would rarely successfully load and most would eventually turn into a "not
found", 500 error.
Here is an excerpt from the log kept by our Process Watcher, the daemon that is
killing your troublesome php5.cgi processes:

Kills prior days:

/var/log/procwatch.log.3.gz:38
Let me give you a bit of background information:
-My site:
Koreanwikiproject.com
-We get around 1,400 hits a day.
-I would occasionally have problems with slow loading and processes getting killed. I
originally thought this was due to people possibly using the pdf converter plugin. However
when I had 1.19 installed, I hardly had any plugins installed as I was doing a fresh
install then copying my image files over.
-No caching has been enabled.
Any help would be greatly appreciated. I will eventually be moving to VPS but I'd like
to make sure this same problem doesn't carry over to the VPS.
Thank you,
Chris
