Sorry, but this is a common mistake... Persistent mysql connections in 
PHP tend not to release associated resources, thus increasing memory 
that hangs around without any use. The first performance optimization 
thing is to use non-persistent connections.

The only case when persistent connections are good is when mysql is on 
another host and tcp is used for connections. For local mysql server 
they do not have any benefits.

256 MB is not much for typo3 system. My server has 2GB and sometimes it 
starts swapping (and I have to tune it a little to prevent swapping).

He can try to install PHP accelerator. This will impove typo3 
performance a lot.
