[ILUG] slow network problems

[HAMILTON,DAVID (HP-Ireland,ex2)]

This kind of behaviour can usually be blamed on duplex settings.
I have seen ftp performance go from 50kb per second to 11mb per second due
to one incorrect setting.
Dunno how to set it under linux though.

I don't think so. And it isn't bad cable, the network is fine under windows
and on the solaris box. And I've tried it on two physical connections. No, I
*think* I have identified the problem - it's the only thing I've found that
comes close anyway. The full duplex setting on the card may be set to "force
full duplex" which the driver doesn't like under Linux. I'm going to try and
set this - I'll let you's know in a few minutes.

Thanks,
Ciaran.
