Just installed Ubuntu 12.04 on my laptop. All the applications are running quite slow, so is Unity and the web browser. For example HD quality Youtube videos are lagging and scrolling down pages lags.

My specs:

  • Ubuntu 12.04
  • 8 GB ddr2 800 MHz RAM
  • Intel core 2 duo 2.0GHz
  • 750 GB HDD

Use Gnome panel, better than unity.

As Firefox consumes much of CPU, many people are complaining of its speed, be it Windows or Linux.

Use Google Chrome browser instead of Firefox. It is very faster.

  • I think the user wants to use OOTB, which includes FFox and Unity or gnome-shell – Thomas Ward Jun 14 '12 at 12:36
