[TYPO3] Server - big enough (Athlon 1.2ghz)?

[Wilson, John C.]

I am not an expert on Typo3 performance issues but I do know a little about
web servers.  If you are running Linux, you should not run X.  Run at level
3 and only run the necessary services.  Also, download and install a php
accelerator add on.  I believe IonCube has one that is free.  This
suggestion will not guarantee that your installation will be sufficient to
handle the traffic load.  I am only giving you pointers that will maximize
your servers' ability.

Yes, I can see that we might run into trouble.
The main problem is that it's very hard to predict the load on the 
server. Maybe it's not a bad idea to try it out anyway. Currently we 
only have a few low trafic sites. So at this point this solution should 
be able to handle it. Then later on, we can switch to another bigger 
server when necessary.

So the biggest question is - if when the serverload is low or not 
significant - will the responsetime be acceptable with this server, - 
will a Athlon 1200mhz cut it for TYPO3? What should I expect?
