I'm pretty sure OpenBSD is (relatively) slow regardless of hyperthreading,

Agree about NTFS-3g, it's next to useless. I've read somewhere that some optimizations are not enabled on OpenBSD.

Still, I like it and use it on my laptop and servers. I'm 100% in line with the first point of TFA : learning OpenBSD is a good investment, you feel that you steadily build up an coherent understanding of the system.

It's getting better, but they still have an older SMP model based on a giant lock
