Did you try using the ULE scheduler?

I had extremely choppy sound, choppy mouse and an unusable system (dual core)
if I compiled anything, but then I changed to the ULE scheduler and everything
got better than it ever was in RELENG_6, particularly sound and DVD playback,
both on dual and single cores.
It looks like FreeBSD is finally also a good real-time multimedia platform.
