Phoronix extensively tested 32, 32bit + PAE and 64bit architectures and they found out that:

1) 32bit PAE mode is never slower than pure 32bit mode.
2) In some case both 32bit and 32bit PAE modes are faster than 64bit mode.

The slowness of 32bit PAE mode is yet another urban myth.

On my 32bit PAE system 32bit Firefox works faster than its 64bit counterpart (I mentioned this fact earlier in this thread but you seem to have neglected that).
