The hit is only when the DLL loads. Windows checks the base address in
the DLL to see if it's already occupied. If it is, it loads the new DLL
at an unoccupied address.

If your DLL loads multiple times, or if you load lots of DLLs, it's
worth it to change the base address, otherwise, it's a "nice to do"

I've never seen any performance hit while *using* a DLL that had to be
relocated, only when loading it.
