This question already has an answer here:

I installed Ubuntu on my Acer Aspire One (2 gig memory, 113G disk available) from the site using the Windows Installer option. It is even slower than Windows. I could make a sandwich in the time it takes to just open up Firefox, and Libre Office is no better.

I thought that Ubuntu is supposed to be a nice fast lightweight operating system. What gives?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

What graphics card do you have? Have you installed drivers for it? – Seth Mar 23 '13 at 21:18
"I thought that Ubuntu is supposed to be a nice fast lightweight operating system. What gives?" Well, it is. Runs much smoother than any other. – mreq Mar 23 '13 at 21:24

Seems you have a problem with your PC. :)

Ubuntu will be a little bit slower if installed with Windows installer as it will be installed on a virtual drive and not an actual HDD partition. But never that slow.

Try running a disk defragmenter from your Windows installation before installing Ubuntu as your Hard Drive might be too fragmented that the virtual drive created for Ubuntu become fragmented all over your physical drive which will definatily make it very slow.

Something else, try to run Ubuntu on your system with a USB drive and check the difference.

It can be really slow when you haven't installed the proper drivers. Else, it rocks on my 2 year old 140$ CPU, while windows lags quite a bit.
