Why modern software is slow

I'm using an ad blocker, and with a cold cache, clicking a Twitter link shows a blue bird for a second, then two blue spinners (center and top) and then after 3 or 4 more seconds I can finally see a message that's a maximum of 280 characters long. News sites don't load much faster. Pages like HN are the exception, and mostly come from the tech corner. I've been on some brand's online store a few days ago and it felt like they want to drive customers away.

But fair enough, it might not actually be most websites, but enough to not be a rare experience either.

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.
