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.) -Sumana

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
