MTU Settings for Ubuntu
Setting your MTU settings adjust your internet connection. With my connection, a default setting of 1500 causes some webpages not to display at all (i.e. Ebay, Microsoft, etc.)
My optimal settings are 1492 to change yours, open a terminal and type:
sudo ifconfig eth0 mtu 1492 (that is eth and zero)
When you reboot, the MTU will return to 1500 – to make it permanent you will need to edit one of Ubuntu’s files:
First type -
sudo gedit /etc/network/interfaces
Then carefully edit your file
iface eth0 inet static
address 192.168.137.10
network 192.168.137.0
gateway 192.168.137.1
netmask 255.255.255.0
mtu 1492
You should now restart your network with:
sudo /etc/init.d/networking restart
Check the new value type:
sudo ifconfig -a

Chrome Stats for Nerds
Chrome has a cool interface (kinda hidden). Open Chrome and open several tabs. Now hit the Shift and Esc keys.
Not only can you see what is using your CPU but your network. The stats details gives detailed information about each of the processes.

Top Processes in Ubuntu
Want to find the top running processes in Ubuntu? Go to the Terminal and type Top. Top will refresh automatically.
Jon Ward ( a former student and a Linux natural) commented on this posting and I’m posting it here because he is absolutely right -
Use htop instead. it’s a much cleaner interface with more precise information. it’s *much* easier to read. ~ Jon
To the readers from me, here’s how to install -
go to terminal and type – sudo apt-get install htop
