Look good.

Also good.

Slow :(

This is really slow. We got nearly 50 rq/s on a *live* server with tv+ 
several USER_INT (non-cached) objects on the page. This for for typo3 4.0.

It seems that you need to tune your server. Check if you have php 
accelerator, it will double (if not triple) the rate. Check if mysql 
query cache is enabled, this gives huge performance increase.

You do not have enough memory: 512M is too small! We have 2GB and it is 
not much.
