No, I don't think so.... my guess is that it has something to do with  
Spotlight indexing, as this issues seems to be new in Tiger, but I  
don't have a definite answer for it.

(To confirm that it's not anything to do with TeXShop, you could try  
processing the same documents using xetex from the conmmand line. I  
think you'll see the same delay.)

It would be interesting to try restarting OS X, and see if the  
behavior is the same with a freshly booted system. I just restarted  
my PowerBook, as it happens, and the ArabJustify example seems to  
typeset noticeable faster than previously. Timing from Terminal:

If anyone who is experiencing this slow-down knows how to use  
performance tools such as Shark to monitor what's happening, perhaps  
we can isolate the cause....
