Below is the trace of my web page. This request is made after the browser is opened. However, When the page is refreshed, the init takes few milliseconds.After this, when i close the browser and open the page again, it is taking 1.5 to 2 secs.
When i keep the browser idle for some 10 mins, and then try to load the page in same window, same tab, it take 1.5 to 2 seconds.

Could some one help me to find why is it taking long time, and how to fix it.. Thanks in advance.

The site is a “ASP.NET Website”, running under IIS7. There are no compiled DLLs. We just host the code in IIS and it compiles when the page is requested for first time.

Thanks in Advance

    It could be lots of reasons for why you are having those performance issue. If you are not using a precompiled web it is normal that it takes longer to satisfy the first request. But after that if the user request the same resource it should be much quicker. It difficult answer you question because there could be lots of reasons why you are having this issue only if the user starts a new session :

    • The browser could have cached the page or you are using any kind of output cache
    • Your code could do something very heavy on the session_onStart
    • we don’t know what you do with each page events
      In general to improve the compilation time you could go for a an Asp.net precompiled web site
      but it not sure it will solve your issue
