Akamai have added some situational performance metrics in their latest state of the internet report.
What’s the situation?
Countries with super fast broadband like Hong Kong have high -what Akamai have called- mobile penalty. A mobile page takes 2.9x longer to load than a page on broadband.
If you stop and think about it, it would be easy to think Hong Kong =fast internet so we can use lots of HD video and we only have to worry about low bandwidth for places like Vietnam. Then you look at Vietnam and see it has the same mobile penalty as South Korea, a traditionally fast internet type place and realise that the gap between broadband and mobile is the thing and not just the total speed.
