What’s the version of `ember-cli` you’re using? Newer versions contains significant performance improvements.

Also, it is a known issue that `ember-cli` has lesser performance on Windows than \*nix operating systems.

**Hi Lightblade,**

Really thanks for your valuable responded. Yes but we need to increase the performance from the old version of ember cli only, because all other activities depends on older version only, except the few;

will try once again and comeback.

+1 on OSX it’s lightning fast for me with a fairly large app.

I ran into issues trying to dev inside a vagrant box but on metal + OSX it’s solid.

My mate uses Ubuntu to dev on and it’s good there too.
