SSRS report viewer loading slow

Question

I'm trying to integrate some of our SSRS reports into our web application. I'm having a problem where the first time the report is rendered is super slow (15-20 seconds). Subsequent reports are almost instant for a few minutes. If I come back 5-10 minute later and try to run a report, it's super slow again.

I've tried messing around in the AppPool for the report server (changing the idle time out and how often the worker process recycles). Nothing seems to help.

This is a common issue with SSRS. You can trigger the automatic reset of the Application Domain by a PowerShell script as this blog explains
