I know we released some high-level aggregate stats from Analytics but I'm not sure if Mobile was called out (will take a look).<br /><br />The Akamai/Mobitest agents that can hook up to WebPagetest can run on carrier networks (and use real devices) but I don't expose any because of costs and highly variable results. Reach out to Guy and see if he has any private testing available.Patrick Meenanhttps://www.blogger.com/profile/16482126817753317557noreply@blogger.comtag:blogger.com,1999:blog-537292020947772033.post-80546525264007472602012-08-22T15:46:18.819-04:002012-08-22T15:46:18.819-04:00I'm most interested in latency as it applies t...I'm most interested in latency as it applies to mobile, where it is a tremendous problem. Sadly worse, CDNs rarely help mobile connections, since the telephone companies usually backhaul over their networks and dump it onto the internet somewhere that is far from your physical location. Unfortunately real world TTFB measurements for these mobile devices is difficult to measure. I don't know of any "mobile performance" test solutions that actual test with real mobile devices over a cellular network. Do you? Any studies about this? Can't find anything meaningful from Google on this.Billy Hoffmanhttp://zoompf.comnoreply@blogger.comtag:blogger.com,1999:blog-537292020947772033.post-82515355609840698902012-08-22T15:37:11.328-04:002012-08-22T15:37:11.328-04:00+1 on latency.

It isn't unusual with the 1.5Mbps DSL connection to see pages that are bandwidth constrained though and it all but goes away and everything becomes latency-constrained once you start going over 2-3Mbps (at least on the tests people are regularly asking for help looking at).Patrick Meenanhttps://www.blogger.com/profile/16482126817753317557noreply@blogger.comtag:blogger.com,1999:blog-537292020947772033.post-13012861931648751842012-08-22T15:30:44.395-04:002012-08-22T15:30:44.395-04:00The shift to faster connections is certainly nice....The shift to faster connections is certainly nice. But it's so easy for people to make the faulty leap that faster connections = faster page load. This is only half the story. Faster connections = larger bandwidth, but latency is the other side of the story. I wrote about this on the Zoompf blog earlier this year, in an appropriately named post "Bandwidth, latency, and the size of your pipe"<br /><br />http://zoompf.com/2011/12/i-dont-care-how-big-yours-isBilly Hoffmanhttp://zoompf.comnoreply@blogger.com
