My Dell have 3GB RAM. In Windows 7, I can easily get 22-25 mbps copying speed but here in Ubuntu I am getting only 7-8 mbps. I even installed zRam.

sudo add-apt-repository ppa:shnatsel/zram
sudo apt-get update
sudo apt-get install zramswap-enabler

this also did not worked.

Please tell me how can I improve my laptop's performance?

Copying from what to what, over what? And why would you expect zram to improve anything related to disk throughput? –  Oli Oct 28 '12 at 22:28

Yeah, I don't think zram would help you at all, unless your physical memory usage is being capped (which it likely isn't for file transfers).

It might possibly be related to the driver in-use for the hard drive controller (assuming SATA). May need more information though, like laptop specs, and/or model.
