Response times varying significantly in MVC app

I have an asp mvc app hosted at www.jacquelinewhite.co.uk. When I use firebug (net tab or page speed) I'm seeing response times of 200 milliseconds for an action that isn't cached and about 30 for a cached action result. However, my reports from pingdom.com are showing an average of between 3 and 7 seconds for a response.

The application is set not to recycle and sits at a consistent memory level. I can't see any CPU spikes and basically everything looks fine, except the response times are a lot slower than I'd hope for.

I'm inclined to think it's not a problem with pingdom and the google webmaster tools shows the sites as slower than 54% of other sites.

Where else might I look at to identify the sites slowness?

Well, as luck would have it, the Stackoverflow team has just released an MVC Profiler (which was originally developed to profile this family of sites). The profiler is available from code.google.com/p/mvc-mini-profiler and also as a NuGet package. You should be able to use it to profile your site and perhaps spot any bottle-necks.

Another useful profiling-type tool is called Glimpse:

"At its core Glimpse allows you to debug your web site or web service right in the browser. Glimpse allows you to "Glimpse" into what's going on in your web server. In other words what Firebug is to debugging your client side code, Glimpse is to debugging your server within the client."
