Wow, the difference between the FreeBSDs and Linux performance is amazing a=
nd for those
looking at the first time on such benchmarks not knowing much about the tur=
bo boost issue
one would definitely choose the faster one :-(

I'd appreciate results of a benchmark considering no boost and with a light=
 sched on the
scheduler (doesn't Linux have a very sophisticated scheduler dealing/scalin=
g very
efficient with lots of threads/cpu cores? This could also be a very interes=
ting benchmark
pointing to AMDs new Epyc platform comprised also from lots of cpu cores).

Kind regards,
