Re: Slow Network - Fedora 16 LXDE - Iptables or NFS

Try (as root) the command "ethtool <interface name>"

The report generated will show (around the middle) the current speed, and the duplex mode. If you see "Duplex: Half" then you are operating at a reduced speed. You should also (just above the "Duplex" entry) see the speed the device recognizes.

ethtool can also set parameters, but I've never needed to change the defaults.

What I get for my internet connection is limited by the router:
Code:
# ethtool p6p1
Settings for p6p1:
	Supported ports: [ TP ]
	Supported link modes:   10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	                        1000baseT/Full 
	Supported pause frame use: No
	Supports auto-negotiation: Yes
	Advertised link modes:  10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	                        1000baseT/Full 
	Advertised pause frame use: No
	Advertised auto-negotiation: Yes

Cpu is not the limiting factor right now, because you aren't doing anything, but it was a couple of minutes ago:

Code:
load average: 0.14, 0.89, 1.29
