8-STABLE performance issues on Supermicro Core i7

[Akephalos]

Maybe this is a ridiculous question, but did you check whether your
CPU is used and accelerated in case you use powerd/cpufreq or another
power-saving feature? I ask you because I had this problem and I
recalled that the same thing gathered my attention in the beginning,
slow compilations. Basically, my CPU was nost scaling upwards for
technical reasons that I can't understand. Here's my thread:
