I was myself wondering about more cores: this is the best I have
recently seen, but cores alone don't crunch it.

Performance is ultimately a combination of many things: many cores, few
NUMA nodes, fast SSD, fast memory. (That hardware has 4x 16 2Rx8
PC4-2666V RAM.)


It also needs better scheduling on the Isabelle side: for this it always
helps if people buy test hardware and grant access to me :-)
