After deploying an ASP.Net application to a new server, the first user to hit the app gets a long pause, presumably because the app is performing its initial compilation. However, this pause seems to also also occur after the application has timed out and unloaded itself from memory.
The first compilation would be tolerable as it only happpens once, but the 2nd one seems to me like it should be unnecessary….is there a workaround to address this issue? It would be nice to be able to extend the application timeout, but I only see a way to extend the session timeout, which I would rather not do, as this would keep all user sessions in memory for a long period of time.
That’s IIS shutting down the worker process – the default is a 20 min idle time. In IIS6, you can configure the app pool and turn off the Idle timeout (on Performance tab). In IIS7, it’s in the Advanced Settings.
