[U-Boot-Users] very slow netconsole

I have u-boot 1.1.6 running on my board based on IXP425 processor (266MhZ).

I trying to use netconsole. I readed doc/README.NetConsole and make connection with u-boot. On u-boot I do: setenv nc 'setenv stdout nc;setenv stdin nc' setenv ncip 192.168.1.5:1234 saveenv run nc On host PC (192.168.1.5) I run following script: nc -u -l 1234 < /dev/null & nc -u 192.168.1.88 1234

Note that in first host command I omitted "-p" flag before port definition. The problem is the communication in vary slow: one character per second!

Any suggestion ?
