Setting up a new instance of SQL Server Reporting Services (SSRS), and getting things configured. What I noticed is that the first time I hit the SSRS site, it would take forever to load, then it would be fine as I used it, and then later after no use, I could come back and it would be slow again till it loaded once, then fast.
My first thing to think of was the App Pool settings in IIS, so I checked them..
The first setting on the performance tab of the app pool, “Shutdown worker processes after being idle for (time in minutes)” is checked by default, and set to 20 minutes. Sounds about right, my SSRS instance would get slow after some time of non-use (20+ minutes)
Uncheck that, and you are good to go. Of course if you have tons of usage, then there is no need for changing this, but on a site you might be building up slowly, you would see the effects of this right away.

Awesome, this took my display time for the SSRS page from about 10 minutes to 5 seconds. Thanks for the info.
