Ok so we concluded its problem with ssl certificate, it slows down website for 3 sec… After instaling ssl on the staging site, it also slowed down the wait time to the same degree. When i disable he ssl, the wait time goes to normal.

This is what i got from hosting support (hostgator):

It is important to understand that static files retrieved from remote locations must also undergo through a https:// request. This includes Javascript and CSS modules embedded within your site’s codebase. At times, these remote hosts do not have your code optimized which causes a delay in delivery over an https:// network since most modules are not designed with that in mind.

I dont know… this seems to much time delay for ssl, they say they checked server and things from their side, and thats everything fine. But i am still clueless why my site slows down 3 sec, after ssl force. I have other websites built on other themes, with the same ssl from the same hosting provider, working perfectly with no slowdown.
