AE performance tip: Don't overschedule your processors

Todd Kopriva performance tip: Don't overschedule your processors,

'This advice is similar in spirit to the advice given in a previous post, "Performance tip: Don't starve your software of RAM."

In many cases, performance is improved by using fewer than the maximum number of processors for Render Multiple Frames Simultaneously multiprocessing, even when you have enough RAM for all of the processors.

After Effects is a multithreaded application that can also use other forms of multiprocessing beyond just Render Multiple Frames Simultaneously multiprocessing, and it is possible for the processors to become "overscheduled" if these threads are competing for the same resources as the background processes used for rendering with Render Multiple Frames Simultaneously multiprocessing.'
