Yes, pre-compilation reduces the time to load an application. This will benefit you on your first request after a deploy, after you've been cycled out or if more application instances are created to scale up with your load. You will see up to 30% improved loading time on your first request. Pre-compilation works by doing a bit of class loading work ahead of time in the App Engine environment before the request comes in.
It's still opt-in, so you'll need to enable it if you want it.
