When I install MediaWiki with Russian language it works very slow (on P-500 pages are loaded in 20-30 seconds or doesn't load at all because of exceeding max. execution time) but when I install it with English language pages are loaded pretty fast (2-4 seconds).
That's a pretty slow old computer; slowness is not surprising. Ensure that: 1) You don't have some generic problem with load, http configuration etc. 2) You have a PHP opcode cache installed (APC etc) <- DO THIS! 3) PHP's mbstring extension is enabled Using memcached instead of the internal db can provide a very small speed boost on a small site as well; assuming you have enough memory to run things of course. Consider also installing the ICU-based Unicode normalization extension which may help with edit submissions: http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/normal/
Thank you a lot, enabling mbstring helped!
