It's possible the poolifying of mbufs did make the performance difference
smaller. It would be interesting to try it again on those machines.

Yeah, the fact it haven't helped a bit annoyed me; I hoped the
change might help make the card actually usable on my machine. The
driver doesn't detect any RX packet overruns with the RX Early
code, but the speed on my 386DX still sucks :( It's a bit irritating
that, according to
the card performs quite well under Linux on 386SX-20.
