I found an awesome page to show you the GZIP results, wow 77%!

http://www.gidnetwork.com/tools/gzip-test.php

Web page compressed? Yes
Compression type? gzip
Size, Markup (bytes) 25,382
Size, Compressed (bytes) 5,626
Compression % 77.8

I enabled it in Configuration , GZIP

But unfortunately my product pages still load slow, close to the same time. Other pages are quick though :)
