Repro steps

• my angular.json file
• ng s --sourceMap=false

All changes take 20seconds to rebuild (in cli 1.6x event 1.7.x I think) I always rebuilded in 3/4seconds.

Here you can see gif of current behavior: When I add comment in a component :

Desired behavior

rebuild time like in old version fo cli (1.6 or 1.7)

I apologize for the node version changes but could you also try with Node 10 (released recently)? Based on some of the changes in V8, it should actually be faster then v8.9.4.

Also, I’m not actually sure why that chunk is out of order. Webpack sorts them internally.
