Mtu
 

I was wondering how I can change the MTU on my nic? I am running a game server and I have heard that by tweaking the MTU I can get better response out of my server. Any thoughts on this? Ohh my MTU is 1500 right now

You can config the mtu size by using the ifconfig command. Do something like:

ifconfig eth0 mtu 1500

Tweaking the MTU doesn't work for everyone and it depends on a lot of issues which setting would be right. Some people report faster transmissions with low MTU settings and some with high MTU settings so basically you just have to try and see if it works.
An MTU size of 1500 for normal ethernet is usually a good setting.
If you use PPPoX then you will definetly have to set your MTU to 1492, sometimes even lower.
