By The Numbers:

The Keynote Mobile Performance Index

How does your mobile website compare? Keynote’s weekly performance round-up for a range of popular sites shows a dramatic spread in response time of nearly ten seconds between the best and worst performers. No sites achieved even a 98 percent success rate. With tremendous variability in carrier network performance, it’s critically important to monitor your site and application performance to be sure you’re doing everything you can to deliver the best possible mobile experience.
