You likely won’t see much of a benefit to using the plugin over using the libpcap wrapper honestly.  Doing the single layer of indirection that is caused by the wrapper doesn’t add up to much overhead.  Bro actually *doing* things causes most of the overhead.

The other small thing to keep in mind is that I haven’t heard many experiences of people using the plugin so the “not widely used code” caveat applies. :)
