I have an issue with Ember.Select views taking really long to render. Ember Inspector gives me rendering times of around 20-30ms for vanilla built in Ember.Select views (http://emberjs.com/guides/views/built-in-views/). That's fine with one or two Select fields but really adds up when you go beyond a few of them...

推荐答案
它是一个问题的ember JS select组件不幸的是，直到1.8.0还没有解决。该问题可能是由于组件为select的每个选项设置绑定的事实引起的，这是一个昂贵的操作。
Its an issue of the ember JS select component which unfortunately has up until 1.8.0 still not been resolved. The problem is probably caused by the fact that the component sets up bindings for each option of the select which is an expensive operation.
There is an issue for this already.
