Extremely slow website on IIS

Question

I'm trying to run a website locally, and it is very slow. Website uses DotNetNuke and IIS7. When I create a new blank website - it runs fast. This particular one is slow.

What have I tried:

1. disabling IPv6 support in browser
2. Change maximum worker processes in IIS
3. I do not have AVG installed. And I disabled firewall and antivirus
4. Remove Ipv6 support in Hosts file
5. Turn off batch in Web.config

None of these helped

Also, my website is even 5 times slower to respond when I need to recompile my solution.

update, if this is helpful, this is my basic trace:

Answer 1

Since it runs fast in production, but slow on your machine, it could be a connection to an external resource, ie database or other.

Enable Tracing in your application and then see where processing is taking too long. You can help narrow this down by adding trace messages throughout your application in places you think could be causing the issue.

You could also see if this occurs on another workstation, with a clean OS, to determine if it could be something on your local machine causing issues.

Answer 2

You could grab the ANTS Performance Profiler from Red Gate and see if it points you in the right direction. There is a 14 day free trial, I've used this tool in the past to find bottlenecks and other issues and it is worth every penny.
