title: What is the biggest performance issue in Emberjs?
body: <p>Last 6 months I'm developing an Emberjs components. </p>
  
  <p>I started had first performance problems when I tried develop a table component. Each cell in this table was Ember.View and each cell had a binding to object property. When the table had 6 columns and I tried to list about 100 items, it caused that browser was frozen for a while. So I discovered, that it is better write a function which return a string instead of using handlebars and handle bindings manually by observers.</p>
  
  <p>So, is there any good practice how to use minimum of bindings? Or how to write bindings and not lose a lot of performance. For example... not use bindning for a big amount of data?</p>
  
  <p>How many Ember.View objects is possible append to page?</p>
  
  <p>Thanks for response</p>
