CLI Compilation is really slow. It completely freezes my computer. Here are the details about my environment: angular-cli: 1.0.0-beta.8 node: 6.2.1 os: win32 x64 Windows 10

I dont know why this issue is closed. The build process is decreasing angular development a lot… in my company we are like 6 developers who most of the time wait on the compiler all day long

I’m using the webpack version, but it’s still super slow on updating.

The webpack branch fixes this. See https://github.com/angular/angular-cli#webpack-preview-release-update for instructions on how to update.
