What's wrong with that? Have you ever seen 2 high performance Pentium
servers with Intel Etherexpress Pro/100 running that "industry standard"
Unix called SCO Open Server 5.0?
1.1 MByte per second - you are getting almost five times as much ;-).
Seriously - 100MBit/s is the available bandwith, not necessarily your
peer-to-peer performance. As other posters stated, watch your CPU usage
and experiment with the window size.
