How is initial render performance currently? If I recall correctly, Glimmer 1.x unintentionally slowed down initial render performance. Has this been or will this be addressed?

There were some regressions, but it's back on par since the last few releases (2.3+ or so).

In addition, Glimmer 2 is near completion, and when ready will provide further speed ups to initial rendering.

We're running Ember 2.2 on Intercom and we've found it to be faster than 1.x. In addition to this, it looks like Glimmer 2 will bring significant render time improvement for both initial render and subsequent DOM updates.
