I have Ubuntu 10.04 server up and running in my home network. Recently discovered that if I connect my notebook directly to modem, I am able to get
1.0 - 1.1MByte/s download speed. But if I connect the same notebook to server LAN port, then I get
0.8 - 0.9MByte/s download speed. Server hardware is more than powerful (i5 CPU with 4GB RAM) and I am not running any special services on it, basically it acts only as router. I have iptables without any traffic shaping.
How can I find where the bandwidth is lost?
Let me know what additional information is required to track this issue.
