Hi,

Good catch Gabriel, to detect the right link 
(https://www.irif.fr/~jch/software/sfu/) behind SFUs word "we 
<https://github.com/jitsi/jitsi-videobridge> evaluated 
<https://github.com/versatica/mediasoup> many 
<https://github.com/meetecho/janus-gateway> open 
<https://github.com/pion/ion> source 
<https://github.com/peer-calls/peer-calls> SFUs 
<https://www.irif.fr/~jch/software/sfu/>"!

Have a good day
Phil

> TL;DR: Signal needed an SFU with good congestion control and scaling properties. They evaluated a number, found that only jitsi and mediasoup had good enough congestion control at the time (it was over a year ago), picked one but it used too much CPU so they wrote their own in Rust. The article gives a lot more technical details about their implementation, but doesn't delve into the evaluation of other solutions.
