iis

Hi,

Every now and then (always after a long period of idle-time, e.g. overnight) when I access a site built using asp.net - it takes around 15 seconds to load the page (15 seconds before I see any progress whatsoever, then the page comes up fast).

Further pages on that site, or refreshes, are quick as usual - they are also fast on other machines, only the first one seems to take the 'hit'.

Page tracing never through anything up (whole cycle was a fraction of a second)

So my question is where else should I be looking? Perhaps IIS? Or could it still be my asp.net app and I'm just looking in the wrong place (the trace) for clues?

As I don't have much control over the IIS server, anything I can check through asp.net would be more helpful, before I go ask that particular admin.

cheers :D
