Do not say you can't do it until you've tried it. Go spend a half hour following the suggestions and report back with what you got stuck on.

Thanks all for replies but I am using w3 total cache, tried disabling all plugins but nothing new.
to be more specific my problem is first byte time when loading the home page.
