[TYPO3] [Typo3] How large of website can typo3 handle?

[Dennis Cheung]

Hi everyone,

I wonder how large, how many pages, langauge it can handle?

I see it do a recursive SQL read for page rootline and template.
Will it has any problem when many pages and a lot of ext template?

May be I ask in another way.

If I did all performance and tweaking,
  what else I can do / patch to get faster?
  what should I don't may let it slower?
