How is this service?

It is like CloudFlare. Need to explore more.

Hi, there are obviously a few elements to PageSpeed, there is the online reporting tool, there are the hosted libraries and there is the Apache module (which I've used a lot). If you're talking about the new beta tool (which *does* look like CloudFlare) then sorry, I've not played with that yet.

In general I do like the look of these hosted/proxy services though. There is so much to be considered with performance etc that if some of it can be offloaded as a service (handled by experts) then I'm all for it.

@Joel, thanks for the inputs. Here is an interesting analysis I found: x-pose.org

And, here's CloudFlare's view:
