SecureAuth IdP Version Affected: All
Occasionally, realm authentication may take more than 20 seconds and ultimately time out.
This could be the worker process being terminated during periods of inactivity. By default IIS will shut down worker processes after 20 minutes of inactivity. In realms which are infrequently used this can lead to a delayed response when requests arrive while the new worker process is spawned and loads up.
There are two changes you can make in order to help alleviate the problem. These can be used individually or in conjunction:
In IIS Manager, go to Application Pools, click on the application pool responsible for the realm, usually called ".NET v4.5", then click "Advanced Settings..." in the right hand pane and scroll down to the "Process Model" section.
Here you can:
1. Increase "Idle time-out(minutes)" to allow a longer time period before the worker process is stopped.
2. Change the "Idle time-out Action" to Suspend so instead of killing the process it is suspended to disk and resumes a lot faster than a normal startup. More info here:
The above will help prevent slow response times when the realms are up and running but you may also be interested in this KB article which explains how to preload and start the worker processes when IIS first starts up or restarts:

Thanks for posting this! I did these steps and the delay loading the page for the first time seems to be gone :) . More testing required to confirm but so far, it looks good
Actually, this is not the article. it was the pre-load article that worked for us. https://support.secureauth.com/hc/en-us/articles/360019885251?page=1#comment_4408223110804
