ASP.NET

Problem

In our production environment, system occasionally delays the page response of an ASP.NET MVC application up to 30 seconds or so, even though same page renders in 2-3 seconds most of the times. This happens randomly with any arbitrary page, and GET or POST type requests. For example, log files indicates, system took 15 seconds to complete a request for jquery script file or for other small css file it took 10 secs.

Similar Problems:

Random Slow Downs

Production Environment:

Windows Server 2008 - Standard (32-bit) - App Pool running in integrated mode.
ASP.NET MVC 1.0

We have tried followings/observations:

Moved the application to a stand alone web server, but, it didn't help.
We didn't ever notice same issue on the server for any 'ASP.NET' application.
App Pool settings are fine. No abrupt recycles/shutdowns.
No cpu spikes or memory problems.
No delays due to SQL queries or so.

It seems as something causing delay along HTTP Pipeline or worker processor seeing the request late.

Looking for other suggestions.

-- Thanks
