Kovács Zoltán sent me a note asking about reducing MediaWiki's memory
footprint a while back and would like your thoughts. (Note that there's
an update below the original email.)

Subject: MediaWiki memory footprint
Date: Mon, 19 Nov 2012 12:52:00 +0100
From: Kovács Zoltán <kovzol(a)matek.hu>
Dear Sumana,
I hope you are doing well. It was a pleasure to meet you at the GSoC
Mentor summit. We talked about MediaWiki performance tuning and you
suggested to contact you if I need further help.
We run MediaWiki 1.18.2 at
wiki.geogebra.org. I am not sure but it seems
MediaWiki has quite a big memory footprint (approx. 85 MB for each
visitor). We don't use any caching yet, but we plan to use Memcached or
Varnish. Do you have any guidelines when to switch caching on (depending
on the number of visitors) and which software does the best job for
MediaWiki? We are also interested in commercial support if the problem
persists.
Thank you for your kind help in advance,
best regards, Zoltan

Update from late December: "finally we managed to solve this problem by
removing the unneeded modules. (Now we don't use more memory than 60 MB
for each Apache thread.) We also started to use memcached but it did not
seem to help too much.
"On the other hand, we are still interested how other people deal with
such problems. So, definitely it would be a great if you could send my
email to the public mailing list."
