Slow rendering of an *ngFor list view

[Birowsky]

The detailed discussion is in StackOverflow: http://stackoverflow.com/q/39778634/592641

But here's the jist of it:

I'm rendering out a list view of quite complex component using *ngFor. 

Instead of what i expected to be out-of-the-dom html construction and single push to render it into the dom, there is a separate appendChild call for what seems to be every little binding in the iterated component. 

The result is almost 2 seconds locked ui on desktop, and almost 4 seconds locked ui on mobile device.

I really hope i'm doing something wrong.

Hi Birowsky,

Can You get me some example code/project that show's this behaviour? As I'm not a codementor, I can't get to your project in there.

If I can't solve this for you, I will put it to the core-team. This is something that needs to be dealt with.

Regards

Sander
