Did you (or prime.txt) do anything non-obvious with assignment of CPU cores to workers? If the old system was running one worker on 012345 and the other on 6789ab, and that's stayed the same for the new system, then worker2 will be using non-local memory and worker1 will be
having some of its memory bandwidth stolen by worker2.

This is consistent with your measurements of worker2 being much slower than worker1 and both workers being slower than before.
