[TYPO3-dev] Typo3 Performance

[Nicolas Cohen]

Hi i did another vmstat while using ab to test 100 requests with 10 
concurrent. As you can see memory stays ok, but cpu raises and goes down.

Here is the result of the ab

Server is idle most of the time now because of the static cache : )

this is the vmstat result, by the way
