Ways to pleasantly surprise yourself: 1. Buy quad core laptop 2. Forget your laptop has 4 cores, assume Intel are still basically only producing 2 core laptop parts 3. "make -j4" 4. Be confused by CPU usage stuck at 50% 5. cat /proc/cpuinfo and spot 8 threads

(I'm a tad curious about this, is it IO bound? I'd have expected NVME to be better...)
There will always be some I/O wait. If you want to saturate your CPUs, it's a good idea to go cores +1 or +2, so there is something to schedule when a thread is blocked on I/O.
