I have use 2GB With Dual Core Processor Computer, and install ubuntu 12.04, Even though the computer is running very slow, All time Show CPU Uses 100 %, and Memory Uses 100%.
So What should i do to speed up my computer.
First, look at gnome-system-monitor
for realizing what's going on. But I think You must install Lubuntu(LXDE based Ubuntu). You can get much higher performance with it on 2GB RAM with a dual core processor.
The difference is just the look. You can run everything that works under default Ubuntu
gnome-system-monitor
and switch to Process tab. And See which process is exploitting CPU (click %CPU collumn). Otherwise, you can see it via top
command.

You can give try to use nmon (Monitor Linux Performance) tools will help you more to reduce the system performance,

You can try Ubuntu Alternative Kubuntu which is based on KDE desktop, I used it and Kubuntu so much faster than Ubuntu:
