With your native angular plnkr example, change ng-repeat to:

    ng-repeat="line in data track by $index"

Now try timing again.

I did try your example, and yes track by $index helps but only on updating the DOm not initial rendering. Post got updated

Interesting update. I never linked ng-repeat to the initial render lag with my app (one page, 1200 - 3000 bindings), otherwise the performance is great.

I've assumed it was a server side issue I could tune before pushing to production. Thanks, now I know where to look.
