    IIS 6 vs IIS 5 ASP.NET Performance Issues


    Hi

    I have currently developed an application (asp.net version 2.0) on a Windows XP Pro machine running IIS 5.

    My problem is that the application runs perfectly with IIS 5, but when it is migrated to different server (better hardware) on a Windows 2003 server running IIS 6, performance degrades a lot.

    I have read several posts stating that using basic authentication and
    changing it to IIS 5 isolation mode would do the trick, but that
    wasn't the case.

    Because it works well with IIS 5, so it is not a coding issue.

    It may be an IIS setting. Whatever the case, I'm completely Stuck.

    Please help/advice.

    You should re-examine this blanket statement.

    Probably you have some other server configuration that's incorrect or some missing component on the new server.

    1. There is no component missing related to the application otherwise it would have stopped functioning.
    2. Other configuration missing: That's why I am here to discuss my problem.

    I used default installation and settings if IIS6 [I used defaults at the time when I was using IIS5]

    There are so many posts on the internet for the this problem but no solution found yet to me. At devshed I am hoping for this solution.

    Check your dns resolver on the server

    Thanks for quick response.

    But I am using IP address to access in intranet.
    Still you suggest this? If yes, please breif how to check dns resolver and what need to be checked. I am a developer, not having much knowledge of IIS and system administration.

    Look at the network settings for your NIC on the server and verify the dns settings are pointing to valid and correct dns servers. Unresponsive dns servers will cause lots of slowness every time a url needs to be resolved to an IP.

    There are many, many, many other things that could be causing your performance issues. Check the server error logs, check your network connection speed, etc, etc.
