Thanks a lot Dmitry.

Are there any downsides to using eAccelerator or turck mmcache? Like making
changes to php files which are already compiled etc. And I read about some
licence problems regarding eAccelerator?

I do have a few extensions, like chc_forum, tt_news, FE user registration,
template auto-parser, jk_poll, content comments, tt_rating, ee_blog, and some
others.

About the errors, the first "not a file" problem dissappeared, when I 
created a
blank php file with the name and path given in the error message... :P
The second similar error persists, even though there is a directory called
uploads/tx_jkpoll/ on the server. Oh well, I guess I have to report 
that to the
creator of the extension.

Any other good suggestions to speed up a Typo3 site? I want to have maximum
performance. :)

Cheers,
Joonas
