Homepage ok now but other pages on the site load EXTREMELY slow compared to homepage

[Vince]

Hello hello,

After adding W3 Total Cache and a CDN(MaxCDN) I managed to reduce the overall loading time of the homepage to about 3sec, it depends on the time to first byte (which i can not seem to reduce and can be up to 2,3 seconds) thanks for all the great info on here by the way!

Here's the result of the homepage http://www.webpagetest.org/result/111116_QT_26RJ9/

Now look at an individual page
http://www.webpagetest.org/result/111116_SS_26RNJ/

I seem to have tried everything but big G gives me an average load of around 6 seconds in Webmaster Tools, way to slow and don't know what to do anymore, please assist!

Cheers,
Vince
