Performance - page is being loaded for the first time vs SubSequent Request

Hello,
I have some serious performance Issues with  Windows controls loading first time on IE Browser then subsequent request's. When ever i open Browser first time , mywebsite takes 7 seconds to load, but on subsequent request  without closing browser it loads with-in 2 seconds.I Knew IIS on first time it re-compiles the process and for subsequent request's  it wont perform and it cahches .I'm looking for better  options to improve performance,  when ever  first time reqest's  comes to web server.
On IIS 7  Server,I was using both Dynamic and Static compression enabled.Also,On application pool ,I set "ShutDown Time(Limit)" and "Startup Time(Limit") to 90 (seconds).Here is web.config i disable below to improve performance issues.
