Hi,

Google told me on GWT that my site is very slow : On average, pages in your site take 15.5 seconds to load (updated on Jan 10, 2010). This is slower than 98% of sitesI have installed firebug and page speed to figure this out, result:

Code:
The following resources are missing a cache expiration. Resources that do not specify an expiration may not be cached by browsers. Specify an expiration at least one month in the future for resources that should be cached, and an expiration in the past for resources that should not be cached:
