Hi! My test results changed a bit. Now I have a speed up when I use 2 server instead of 1. Try to find out what the difference was in my code.....
Next tests will be with real data. Pyramid field seems like a killer test for SortFirst. Okay in each direction during rotation comes some thousand points in z depths... 500x500 pyramids with an abnormal height... so it's more like a filled cube.

There is no built-limit, so that is surprising. One reason I could think of that would explain the effect is if you change a part of the actual geometry per frame. That would force sending the whole geometry over, which will take longer with a larger object. Can you check to make you don't do that?
