I've only done it once (the way they have it architected, it's a "set and forget" sort of thing, your LB changes don't touch the Global Accelerator) but I do seem to recall that it took awhile to create the resource. Maybe 5-10 minutes?

5-10 minutes is accurate for creating and rolling out changes to a Global Accelerator
