Why is the Angular example template without any modification so slow in production?

It takes about 1.06 sec to refresh http://localhost:5000/home on local server.
How can this be a Production quality example?
1 second is too much. For most of the server admins this is not acceptable.
I am using DotNetCore version 2.0.3 on Windows x64.
To reproduce: (just the basic, without any modifications):

"dotnet new angular"
"npm install"
"dotnet restore"
"dotnet run", which says: "Hosting environment: Production"

In Chrome browser, press F12 and go to Network. And Paste http://localhost:5000/home to URL field.
Then hit Refresh sporadically. For getting the "home" or "localhost" document which is 6KB the query time is:

1st Refresh: 2.5 seconds. // Fine. First time the preparations take some time.
Hit Refresh very quickly (in every 2-3 seconds): 45msec
Hit Refresh while waiting about 5 seconds between Refreshes: 1.06 sec

So, it is 1 second in general for a random user accessing the website with some infrequency. With local webserver! Is it the best we can do?
Could you enlighten me why it is that slow or fix it please?
Thanks.
