That's usually relatively expensive. So you will almost-for-sure get some kind of improved performance out of the change. You could try comparing an exec() of a MUCH simpler ImageMagick call with the corresponding PHP script to compare the two on your hardware. That said, if the time is all being spent in the guts of ImageMagick doing pixel mainpulation, then switching won't help much. You could also use valgrind/callgrind to see where the time is being spent, though it might be easier for a newbie to just hack up a PHP script and an exec to compare... -- Some people have a "gift" link here.
