I think it's a libpcap bug, actually, and I think I sent Craig Metz' diff that fixed it to Marcus some months ago. But he's a busy guy, so it's possible he didn't see it.
Anyway, if libpcap stops doing stupid things (reading more data than it needs to, not using the in-kernel packet filters, etc.), the performance will improve. I don't know what version of libpcap NFR is working with these days, but it might be worthwhile for someone to find out and tweak it to do the right thing.
