Expected behavior
Second compile time must be below 1 second. But It takes 3 times longer than first compile.
There is no problem when compiling with angular 6.1

I thinks this isn't duplicate of #21361. Because yesterday I haven't any issue when using angular 6.1. After upgrading to angular 7.0 I have met this compile time problem.

npm install @angular-devkit/build-angular
