In addition to utilizing most of the lab computers, we've added a dedicated render farm. 168 hyperthreaded cores and 336GB of ram. It's already having a huge impact on the images we're making.
So when the entire system (farm+lab stations) is maxed out, we can run 138 frames simultaneously, each with a memory cap of 8gb. If we had less demanding memory requirements, we could split and double or quadruple the concurrent load. So that's 138 times faster than a single machine.
