We've been experiencing sporadic performance issues with one of ours ASP.NET sites.
I set up failed request tracing to log any request that takes more than 15 seconds.
What I'm seeing is, these events are taking the most time:
- AspNetGetAppDomainLeave
- AspNetStartHandler
- AspNetGetAppDomainLeave
- AspNetStartHandler
- AspNetMapHandlerLeave
- AspNetPagePreRenderLeave
- AspNetSessionDataEnd
- AspNetPagePreInitLeave
With AspNetGetAppDomainLeave being the predominant one, usually taking between 11 seconds to 15 seconds.
Can anyone help me to interpret what these events mean?
Thanks
