Turn off hyperthreading, run a uniprocessor kernel rather than bsd.mp. I can't immediately tell if you're running i386 or amd64, but i386 will probably be better. There may be something else going on here, because 150kpps should be trivial for a box like this, but the advice above will certainly improve your situation. (Yes, it will hurt to know that 7 of your cores are doing nothing. Too bad, they're just slowing you down now)
