The network stack already has priority over user processes,
except when executed in process context, so preemption has
no direct impact on briding or routing performance.
Well, NAPI puts a lot more of the packet processing in
process context, including the code that would do routing
I believe.
To give networking more priority, you can re-nice the ksoftirqd
process(es) to a high-priority level like -18 or so.
You can also reserve more memory for the networking stack
and increase the size of the permitted buffers.
I am also interested to hear how your system responds to compiling
w/out PREEMPT.
