Sure. Here we go:
perf stat on first PC (i7-6700K @ 4.00GHz x 8 CPU, 32GiB RAM):
395,282.24 msec task-clock #5.612 CPUs
utilized
4,982,318 context-switches # 12.604 K/sec
1,258,234 cpu-migrations #
Just out of interest: can you run
perf stat yourprog
(depending on your setup that may need root or a temporary adjustment of
the paranoid setting) on both machines and share the results - just to
know what we're actually talking about...

Your application does not run multi-threaded under Valgrind, see
https://valgrind.org/docs/manual/manual-cor
The program being tested is not single-threaded. In fact, it is "extremely"
multi-threaded. That's why I was expecting faster runs.
