A single-processor system with low latency is what you want-- try to shutdown USB or anything else you can which might generate interrupts but the NIC (and a serial port for the GPS/PPS signals, if you've got a clock).
OTOH you can have the interrupt/PPS signal handled on a single processor and the rest of the OS junk on another processor - reducing the work (and therefore the latency) involved.
Might need a custom kernel to tie the interrupts like that though.. not sure if the OS can do it by default.
