[ECOS] eCos TCP/IP Performance

Hi All,

I am researching several RTOSs and processors for an ethernet
application.  The application is a board that takes serial MPEG-2 data
at up to 32Mbits/sec and packetizes the data for transmission over UDP
on Fast Ethernet.  eCos looks very promising as a RTOS for our design.

I am looking for UDP or TCP performance data for the processors and/or
platforms supported by eCos to be sure we can handle this throughput.

I searched the archive for this mailing list and found one post that
addresses TCP/IP performance.  The author (Richard Wicks) said he was
able to get 20 Mbits/sec on a IQ80310 board with an Intel XScale
processor running at 600 MHz.  He also said that under VxWorks he was
able to get 40 Mbits/sec.

Does anyone else have UDP or TCP performance numbers for the various
platforms supported by eCos?  Is a 600 Mhz processor really necessary to
get this throughput?

Our application will be packetizing the data close to the maximum
ethernet frame size of 1500 bytes.
