First of all, VB is precompiled and PHP is not. This will already be
slower. So, you gonna need to create a logic that loads only the
necessary classes for every request. In VB you wouldn't probably need it.

Good idea.

Depends al on the logic you will give to it.

500 queries wan't really matter because it has few to do with OO/PHP.
60k of code, if all together on the same request will be definitely slow.
So, make sure that *only* the required classes are loaded on each
execution.
