Good to know. I didn’t know the contest has no limit on hyperthread.

1brc in the contest had SMT disabled [0]. (hyperthreading is an intel marketing name and trademark for their implementation of smt, but the benchmark was run on an amd cpu)

Ok. So it's indeed restricted to 8 core (1 thread per core). Then the benchmark above using 16 threads was not really a fair comparison.
