As i checked on google, pagespeed measures mobile and desktop sites using "Emulated 3G network". As per some GSMA report from 2016 that 75% or users are on 2G/3G networks.
Thats almost 2019 year and many users are on 4G now, so reports are useless.
Can someone tell Google that either they should use "No throttling" or add switcher for 4G network.
回答1:
Per GSM report for 2017, 71% of Global users are on 2G/3G network. That number drops to 32% for North America and 59% for Europe. While we are definitely moving toward 4G dominance (predicted by 2025), it seems too early to ignore such a big part of consumers.
回答2:
If your business have customers buying from 3g networks then take page insights data into consideration. Otherwise just don't look at them, they are misleading for most use cases. Google want us to believe we live in Africa all together. Note they are also emulate a moto 4g, a mobile phone from 2016 for their tests. Another fail for the modern era.
