I just checked twitter's network log on a single tweet by John Carmack.

- 131 network calls

- 280 kilobytes of data received

- 4500ms total network time

Thankfully, the vast majority of other websites aren't nearly this bad, but we're trending towards twitter as an industry, not away from it.

I try to write API calls that provide broadband utility and return lightning fast by always making sure my critical path gets a fair shake for optimization, but I know there exist calls out there in react land that take my 220ms response and spend an extra 7 seconds transforming it to populate a (paginated) table on the UI.

Amount of data transmitted seems fine...but 131 network calls? No wonder it always feels so slow to use Twitter.
