Need help to improve Page Load Time

[vinitj]

One of my pages result is
http://www.webpagetest.org/result/150125_4V_WC6/


It takes around 7 seconds to start rendering. However its come with around 90% visibility

How can I reduce the 7 seconds to few seconds only.

I have a Managed VPS server and am using Compression and Caching on my server.

The site is built using Jquery UI and there are too many JS and Css that needs to be loaded. How do I defer or get rid of these mandatory files to improve my 7 seconds to 2 - 3 seconds.

Any other help / guidance to get this down to 2 to 3 seconds from 7 seconds.

Similary, another page report is

It also takes around 5 seconds to start rendering with 90% visibility
