I don't know what (if) I read this in any books or mags. I would recommend MacTutor(name may have changed) I had read it all through college and worshiped it. You can find it at *the Book Stop* if you know where on is. You can benchmark you routines fairly easy. Before you call your function get the ticks off the clock then again afterwards, then get the difference. ie ... start=GetTicks(); /* I think this was call, check the toolbox */ foobar(); total_time=GetTicks()-start; ... One more thing, I left out another optimization kludge. Try to reduce the number of calls outside your function by moving the code it is calling to inside the function. This reduces the associated overhead of jumping (jsr $xxxx). Also, if you have to go through the "toolbox" check into the function GetTrapAddress(). Do this for Moveto(x,y) and then you can bypass the entry point of the toolbox and go directly to the routine in ROM. This should shave off 5%-15% on the execution of toolbox calls. DO NOT HARD CODE THE ADDRESS IN YOUR PROGRAM! YOUR PROGRAM WILL DIE A HORRIBLE DEATH ON ANY OTHER MODEL! Use GetTrapAddress(). Hope all this helps. Let me know how things work for you.

I saw your list of recommendations for code speed-up on the mac. I'm currently learning how to program the mac, make tool-box calls, etc. and I found the list interesting. Is there book of information like that, or is this just stuff picked up in the trade? Let me know when you get a chance.
