Things have gotten a lot better over the past few months:

* Meteor has added quite a bit of functionality

* The cluster package has simplified scaling a lot

* Template level subscriptions are making it easier to build reusable reactive components

* The quality of third party packages is improving as more developers are contributing and reaching a level of proficiency

As far as "high performance", it's a node app... so you have all the plusses and minuses of node. I think Meteor is way ahead of the curve compared to other platforms (think Zope, Rails, Django, Drupal) for it's age.

I'm building several apps with it now including a WebGL CAD app and a mobile job search app. Performance is actually surprisingly good for the CAD app and the job search app runs as fast as the apis it sources data from will let it.
