问题
I have a new .netcore web app deployed to a windows server 2008R2 IIS instance, and after the app has been idle for a while, it's slow upon first load, and then subsequent requests are super fast.
In previous versions of .net I changed the Idle Time-out property of the app pool in IIS to 0 to fix this issue. Is there a similar setting somewhere with .netcore, perhaps something I've missed I could add to the Startup.cs file?
回答1:
Baring there being a legitimate fix as I am unfamiliar with .netcore; writing a route which returns an HTTP 200 or something as a heartbeat and then calling it from a scheduled task every X minutes(idle - 1) would prevent the application from ever idling and thus keep it from slowing down requests.

How about setting up the Application Pool Idle time on IIS?
Also make sure the recycling settings are unchecked
