LATENCY, mostly TOTAL LATENCY

[Dimitri Muskens]

Thanks much to Dimitri for the insight on how Jamkazam works. Knowing that Jamkazam clients communicate peer-to-peer sheds a lot of light on the whole subject. For example, it perhaps explains why 2 players seem to be able to play together in sync while a third player drifts off the beat.

I'm still thinking that the Jamkazam clients all communicate via UDP because, since UDP is connectionless, it inherently has lower latency than TCP.

Anyway, getting back to my original post, I'm trying to determine if I should switch from my current ISP (AT&T twisted pair) to Metronet, which touts fiber to the house. My neighbor 3 doors down has Metronet, but is not a musician, so trying a jam from his house is not an easy option. Therefore I was trying to come up with another way to test if Metronet will give me better latency, before I go through all the hassle of switching ISPs.

There's absolutely no discussion nor secrets about the connection protocol used by Jamkazam. It is most definitely UDP.

Fibre/fiber/glass is always going to be superior to any copper/coax connection.

As far as testing from a neighbors house; your laptop with JKZ, audio interface, headphones, any instrument and/or microphone (so not even a shopping bag full) and a knock on his door, will tell you everything ... ;-)
