So you're saying that Google's official browser is slow on their official web technology on their official mobile platform? And Samsung, who is well known for their software quality issues, is a better choice?
Well, he is speaking from experience. While this isn't the place for speaking from experience but more about enabling a better experience for all users he cannot deny what he has observed. However the user above us had the correct answer with filing a bug / legitimate issue with devs. That is the only way to increase usability for all users.
Samsung's browser (and several other competitors) are faster on Android because they contain closed source rendering that's customised for their chipsets. Google can't integrate the closed source code into Chrome because they'd effectively have to fork it from Chromium to do so.
Doesn't Chrome already contain close source code? I thought it was chromium plus Google proprietary code. For example, some features are available only on Chrome (DRM etc. "features"). If they wanted, they could optimise for a selected few top selling devices.
I thought this was common knowledge. Chrome is horrible on Android. If you look at benchmarks, the only browser/phone combination that is close to iPhone Safari performance is the latest galaxy flagship running Samsung Internet.
