With Windows 7 I got a 50% improvement by turning off Encrypting File System (EFS) for the project's /tmp directory. (right-click Properties->Advanced->Encrypt contents...)

For later versions of Ember CLI running in admin mode as mentioned here and suggested by D-Go in his answer seems to be the way to go, assuming your company allows this.

If like me you are using GIT Bash to run Ember you may be interested in how to set it up to automatically run in admin mode here
