Hi,
We are working on an appliance like product that is based on OpenBSD.
Recently we found out that our performance critical C++ program is
~2.5 times slower on OpenBSD compared to Ubuntu 20.04.
The program basically just reads data from stdin, does some

Thanks for the fast answer guys.
Luckily my motherboard (ASRock G31M-VS2) has

I'll experiment with
