Because of the aligment constraints of the card, its copying every single packet the driver recvs. This is required on alpha (and possibly other platforms) to prevent an unlaligned access. In a forwarding situation on an x86, it is suboptimal. Try making the m_devget in the rcv handler conditional on !i386 (see http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/nge/if_nge.c.diff?r1=1.13.2.2&r2=1.13.2.3 for an example of how to change this) I'd be interestd to hear (quantitatively) how much your perf changes.
