It depends very much on what you are doing.
I'm working on a fairly complex 3D application that both rely
heavily on math calculations as well as massive amounts of drawing
on the screen. All in all I have to say that the UB expected UB
performance boost is more or less non-existent, with a few
exceptions. VectorWorks, for example shows a 2.3 times speed
improvement, to mention something similar.
I compared a 1.6 G5 with an Intel iMac 1.8. All in all, and
including compensation for the clock speed, it redraws are about 15%
quicker on the Intel Mac when compiled with the 2006 R4. When
compiled with the 5.5, I basically got exactly the same speed as the
IntelMac on the PPC machine, as it typically generates code being
10-20% quicker than the 2006.
In other words, and despite islands of speed improvements, the
general performance of the 2006R4 is not very impressive. It works
OK, but does not shine in any way.

Thanks for this appraisal, Claes!
As one who is about to buy a new Intel Mac laptop (Come on Apple
release the new Core Duo 2 chip already!!!) I'll adjust my RB
expectations accordingly. Compiling my current large app (PPC IDE on
1.6Mhz G4 laptop) isn't dreadful, but it isn't RB5.5 let alone Rb4.5.
