[microblaze-uclinux] Performance with EMAC core

["Kapp, Steve" <SKapp@xxxxxxxxxxx>]

Has anyone gathered hard numbers concerning network performance (either raw
or TCP/IP) when using the Xilinx EMAC core. We are running the Microblaze at
72 MHz (yes that includes the OPB) and can only transmit (UDP traffic via
netcat) at approximately 350 Kbyte/s, or 2.8 Mbit/s. Our test setup uses a
100 Mbit/s link on a point-to-point network with a dedicated laptop. 

Any and all hard numbers would be appreciated, as would be tips for
increasing performance. I have read some of the Ethernet related posts in
this mailing list over the last two years. None of them spoke of high-speed
networking. Our goal is a sustained 3 Mbyte/s over UDP and right now we are
an order of magnitude away...

Regards,

   Steve
