I have develop an asp.net-core MVC 3.1 application.
This application is hosted on a Linux server.
This webapp is launched by systemd with this command:
/usr/bin/dotnet /pathto/myapp.dll
I have an nginx web server which act as a proxy: Here is my nginx site configuration:
location / {
proxy_pass http://localhost:5000;
...
}
Here is a description of my problem:
- The application is very slow on the first page (about 30-40 seconds. I have a very basic sql server command on this page).
- Then the application respond quickly (1 second).
- I can go back on the previous page, the application respond quickly
- I wait about 2 hours
- The first page is slow again.
I am wondering something: Is it possible kestrel deletes at some interval compiled cache or something like that ? And when a user hits again the first page, kestrel compile something on the fly ?
This is strange because my app is stilled compiled (dlls)
Thanks
