Too slow network connection.

[mcfly]

Hi

I have a server running Gentoo at a remote hostcenter.
My network speed has dropped alot. I can only download with 20K/s it should be around 500K/s the hostcenter testet a file download from the server, and got the same result.

The funny thing is that I can start multiple downloads and still get around 20-30K/s on each.

Could I have done something to cause this? and what?

if you have direct access to this network interface,
you could check your interface with

Here are the outpus from both my interfaces. It is the eth0 that is in use.

hmm, everything seems to be right....

What could be wrong then?
Could it be the driver or perhaps something in the kernel.
Do you think it might help to try the other interface?
It is really strange the way I can only get 35 K/s on one connection but twice that if I establish 2 connections.
