I noticed the exact same thing on windows 10

[paulstelzer]

Did you tried it with ng serve?

[giacomocerquone]

@paulstelzer yes, it's slow as hell too

[dylanvdmerwe]

Apparently upgrade to node 10 and try again.

[giacomocerquone]

Yes I confirm that updating to node v10 solves the problem. if @alan-albuquerque gives confirmation of this too, where can we write this info in the doc?

[alan-albuquerque]

Yes! Upgrade to Node v10 worked, thank you.

[alan-albuquerque]

Is this a bug or a documentation problem? I see another bug report for this problem today (#15868) and I guess that more will be open in the future.
