Well, that you can probably forget. :-(
Using a program that sends 1500 bytes udp packets as fast as it
can we get 22-23 Mbit throughput (50MHz 860T).
On vxworks the same program gives about 27 Mbit throughput, and
Windriver claims this is a limitation in the hardware...

(Our PII server connected to the same hub gives about 91 Mbit)
