While I agree React isn't the issue here, you chose horrible examples. Loading Facebook on my computer (especially trying to open a chat window) brings my computer to a knee. And using twitter on mobile browser you quickly learn how the spinner looks.

I haven't had performance issues on Facebook in quite some time. And Twitter works like a charm on my Nexus. I'm wondering how much of your issues have to do with either round trip latency or network issues.

  Using FB on my 2014 Macbook Pro is slow as hell and my CPU starts heating up causing the vents to spin up. It has nothing to do with the round trip latency, the CPU is pegged.

  The Twitter PWA works fine on my crappy $200 Android phone.

Same issue here, I think it takes on average 30 seconds to open Messenger. Facebook is similar. Twitter is also slow.
