I have two Threadripper 2 2990wx computers (217.6 Ghz each) and a dual Xeon E5-2630 v4 computer (88 Ghz). All three have 64gb of RAM.
When I render a scene I have built on all of the computers, the Threadrippers are averaging between 40% to 60% CPU utilisation, and in some moments, I have seen the utilisation go down to almost 20%. The dual Xeon is always at 100%. I'm using Deadline to render with no UI, and the Threadrippers are completing renders only around 20% faster. I would expect the Threadrippers to be over twice as fast, or is there something I missing?
