Mumble: Open-Source, Low Latency, High Quality Voice Chat
We ran a mumble server for a 3,500 user, paid/paying, video game server community (Battlefield 3, circa 2010). We typically had 200+ users on, with 30-50 users per channel (three servers, two channels per server) plus a handful of regulars in the hangout channel. People would stream the same video on netflix and chat with eachother. It was quite the community.The server ran on a "free-tier" server that the hosting company gave us for free, since we were renting three of their top-tier gaming servers. It used, at peak, 5-7% cpu, and 250mb memory, if I remember correctly. Normally it was closer to 2% cpu and 100mb memory. This was with all the settings jacked up to "ultra" or the equivalent.Audio quality, and latency were amazing. It's really disappointing to use video chat like Google Meet, or Zoom after a product like Mumble.My servers & mumble server finally got retired, but some of the regulars started their own server, and occasionally I'll login still and a bunch of them are still hanging out. Mumble is an incredible, extremely stable product. Highly recommend.
