it heavily depends on the kind of processing your software performs.
Bottlenecks could be the database, the file system, the memory occupation.
Less likely it could be the processor.

Can you assume that those accesses are reasonably distributed in the 24
hours?

BTW

A comprehensive evaluation would require to take into account a lot of
parameters involving many entities (HW, OS, DBRMS, Typo3, Apache)

That said, the most important thing to look at when using Typo3 id if
the pages of the web site you develop can be put in cache by Typo3.
For example there are certain extensions that when their plugin is used
make a typo3 page not be cacheable.

At the T3CAMP Italy held a few months ago in Bologna , I saw a very
interesting presentation made by Mauro Lorenzutti on this matter.
