.net website slowness when there is low traffic

[Joe_Yusko]

I have a problem where some of my .Net apps run fine on my web servers during
average traffic, but when that site gets little traffic, they respond much
slower. My thinking is that after some inactivity, .net unloads components
and stuff that it doesn't need.

So if my site is idle for say an hour and it finally gets a hit, the
response to the user can take upwards of 20 to 30 seconds, whereas with
normal activity, response time is 2 or 3 seconds.

Any hints, configs to IIS or .NET or thoughts are most welcome.

Thanks!
