Dear Tampi,
Whether both processors are running is dependent on the operating system
version -- if you boot your machine in OS 9.2.x, the second processor is
ignored except for software that is explicitly written to take advantage of
it (such as PhotoShop). Thus, this is the easiest way to ensure your times
reflect one sole processor. Unfortunately, if your software is OS X-specific,
then this becomes problematic.
The other question is what type of DSP-based manipulation are you doing?
Are you sure it is handled by the processor at all, and not by a DSP in a
VSLI chip?
Best Wishes,
