8-STABLE performance issues on Supermicro Core i7

[Bryce Edwards]

I have tried both drives independently (two system drives currently
in ZFS mirror), but the interrupts was something that caught my
attention as well.  I haven't yet tried polling yet on the em
interface, but I still have interrupts like what you are seeing (minus
the em ones) when I'm just compiling and not really using the network,
so I was going to wait before going down that path.
