I am not sure if this is the right forum but I'll ask anyway. I
understand that 64bit Windows uses WOW64 to emulate a 32bit environment
for 32bit apps on 64bit OS. The following are my questions.

What are the disadvantages to doing this?

Does this degrade overall performance on the system?

Is the 32bit application still limited to the 32bit memory address space
or does the emulation somehow change this?

Can you point me to some additional documentation regarding this
emulation environment?

Thank you.

Megan
