[ECOS] eCos TCP/IP Performance
Mon Jan 21 07:11:00 GMT 2002
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.
