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.
