> Moving to a CDN doesn't have that impact. It shaves off 10-100ms across the board.

I think this is where we disagree. I've seen (firsthand and through analytics) situations where using a CDN can dramatically improve response time in a small subset of customers (while also getting the across the board win for most customers).

I've also seen CDNs (Amazon's in the early days) that were signficantly slower than direct to linode, even with a warm cache. It's a weird world, and packet routing is hard.
