How to speed up asp net core application startup?

Question

ASP.NET

I wrote an Http server that receives a post request to the address I need. The first response from him comes after a rather unpleasant long time, later everything is fine - the server responds in the same second. What should be entered and where, so that after restarting the server is already ready for quick responses?

Answer 1

If hosting on linux, try using HealthCheck
https://docs.microsoft.com/ru-ru/aspnet/core/host-...
along with BeatPulse
AND pull it curl every 5 minutes.
If IIS then try this

Answer 2

nothing and nowhere, this is normal behavior when the application starts, all resources are initialized there, connections to the database, if any, and so on.

Answer 3

Looks like an unresolved issue: https://github.com/aspnet/Hosting/issues/809

Answer 4

perhaps this is a "cold start", there is such a feature "Always on", when it is active, the server does not unload the code from memory and always works, but this is available on a paid server.

Answer 5

You can try:
1. in the application publishing settings - File Publish Options, check the box "Precompile during publishing".
2. install the iis component - "Application Initialization" (where the Windows components are)
3. in the ApplicaitonPool settings, set the Start Mode to AlwaysRunning.
4. in the website settings - Preload Enabled = True

Answer 6

this is from the time of iis. there it is necessary to put a tick, the bark is a flag. I don't remember now but something like this https://serverfault.com/questions/683017/first-req...
