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 ?
