TYPO3 does not have very effective caching mechanisms outside complete 
page caching, so if you have personalized views (like the username on 
every page), then those will be slow. And if this makes up most of the 
site, then TYPO3 is probably not the right tool for the job unless you 
seriously improve the caching mechanisms yourself, which seems 
impossible for you as a newbie.
