hi,

we have installed php eAccelerator, activated mysql query cache turned 
on and done all documented optimizations. Still we get 1.52 
requests/second. I don't understand why do i need more RAM to get an 
acceptable result. I am not looking for 50 requests/second. With 10-15 
it would be ok.

Anyways, using the static file cache extension seems to do the trick, 
though i still know that typo3 is not giving a good dynamic performance.
