100ms becomes significant if you're doing teleconferencing or other real time interaction. If we somehow improved latency and jitter on the internet generally, I think that'd do more to improve its usefulness than expanding bandwidth. And don't forget about the studies out there that show a relationship between load time and revenue in e-commerce: "A 100ms decrease in checkout page load speed amounted to a 1.55% increase in session-based conversion."

If doing realtime interaction it's unlikely they'd negotiate more than one connection (reusing connections or not), so the test they've done hardly seems useful. I also have huge issues with a lot of those studies; 100ms from 200ms -> 100ms is immensely different than 1500ms -> 1400ms.

This is 100ms for establishing a TLS connection - that's not the same as 100ms latency for all of a video stream.

  Oh yeah, you're absolutely right. I got a bit tangential. Slow establishment wouldn't matter for a stream. I'm sure it's something more like the e-commerce page load time vs conversions scenario for OP.

    I could live with slow handshake, but it's ~110ms for every request.

      I had a similar problem working with an managed file transfer service. Lots of small files would get bogged down by these sorts of issues. The other side of the connection wouldn’t change their config, so I implemented a proxy that maintained session state on our side.

Teleconferencing is a good example of where this does matter, although I'd suggest that despite the current situation we're all in, it's not a significant part of the industry. > And don't forget about the studies out there that show a relationship between load time and revenue in e-commerce: "A 100ms decrease in checkout page load speed amounted to a 1.55% increase in session-based conversion." This is true, although I believe this relationship doesn't hold when you're moving from 200ms to 100ms, it's more for when you're moving from 1000ms to 900ms.

Latency is capped by two third the speed of light. The network latency is actually pretty good overall considering this (the issue is really on the user end with terrible Wifi and mobile connections). The speed of light is quite impactful when you're looking at different countries or continents.

  > Latency is capped by two third the speed of light Starlink: hold my beer. I'm not a HFT, I know I can't increase the speed of light, I know I can't tunnel through the earth to shave a few microseconds off a transmission. I can appreciate the difference between 300ms rtt and 900ms rtt - the later being a practical minimum when you're coping with outages in the 100-200ms range and networks reroute. Give me jitter over drops any day.

Yes, this is a real time platform. I spend some of my dev time optimising performance.
