If you want to improve your web site performance, you should enable GZip compression.

What is GZip compression ?

It's simple : you zip date before sending it over the net :
  1. Server compress data (HTML code, CSS, JavaScript...)
  2. Data go through the net
  3. the navigator uncompress data when it arrives before showing them

It's describe in HTTP/1.1

Is performance really better ?

You can check it here :
