Terminal Server 32bit /PAE vs 64bit

We currently are running 2 win2003 EE sp2 terminal servers in an active
directory domain that get their romaing profiles for the TS users from the
DC. We are now running into performance issues (cpu/memory) as it seems
from the task manager performance monitor that we cannot use more than 3.9gb
of memory even though we have 9gb installed and have a 13gb page file
(suggested by windows) and have the /pae switch enabled in the boot.ini
without the /3gb switch.

My question is that does not the /pae along with win2003 EE give the ability
of using up 16gb like it says for our applications. Our applications are
32bit based an I know about the 32bit limit of memory addressing but is that
not what the /pae and win2003 EE supposed to address. Or does 64bit win2003
EE actually give you that through the WOW emulator to 32bit applications.
