You want SMC Etherpower II NICs:

ttcp-t: buflen=8192, nbuf=2048, align=16384/0, port=5001  tcp  -> lyssa
ttcp-t: socket
ttcp-t: connect
ttcp-t: 16777216 bytes in 1.44 real seconds = 11374.44 KB/sec +++
ttcp-t: 2048 I/O calls, msec/call = 0.72, calls/sec = 1421.81
ttcp-t: 0.0user 0.3sys 0:01real 25% 0i+0d 0maxrss 0+2pf 7541+0csw

That are two PIII@700MHz with BX boards and SMC Etherpower II NICs.

No good idea. Both of my tulip cards (SMC 9334, D-Link DFE500TX) tend
to fall back to "store and forward" mode very quickly with the "tlp"
driver. And afterwards the send performance is below 8MB/Sec on a
100MBit/Full Duplex connection.
