Nice to hear!

You might want to file a bug so we can investigate the build time regression. Erik's been working on some infrastructure improvements to make whole-module builds more parallel, so if you want to live on the bleeding edge, you might give the 3.0 snapshots a try and see if build time is more survivable.
