After Effects CC on a huge machine never really passes 25% cpu power.
I have a Large workstation, Win764bit, SSD drive, 24 G RAM 12 cores. And AE flies on small files but on large one it never really does pass 35% cpu power. I cant imagine the bottle necks. Any one else noticed this? Multiprocessing is on

What are your current multiprocessing settings? My starting point is generally to leave a quarter of RAM available to other apps, and pretend that hyperthreaded cores don't count (leave at least half of the CPUs to other apps -- sometimes more).

I can nearly peg the processors in my 12-core HP Z800 with 48 GB of RAM with the following settings:

RAM reserved for other applications: 12 GB
CPUs reserved for other applications: 12

I generally change RAM allocation per background CPU based on experience depending on the resolution and layer-heaviness of my comp.

Remember, the goal is faster renders, and that's not always the same thing as high utilization of any given resource. That said, we generally try to make the CPU the bottleneck because it's the hardest component to upgrade.

I have 24 Gigs of ram. So I think I should make a goal upgrade to 48.
I just saw this video that was encouraging.

Another compositor said that's the difference between "AE and Nuke". I guess I looked for that comment.
