I tried setting up a Jitsi server for around 400 participants (with audio and video turned off for everybody except the host).
Intel Xeon Gold 6140 (32 threads)
192 GB Memory
700 Mbps bandwidth
My conference was scheduled at 10 AM and for some weird reason, the disk I/O fell to near zero just as people starting coming in.
Even though the CPU utilization hovers around 15% and the bandwidth, memory usage is negligible, the number of processes waiting for execution (Load Average in the attached picture) spikes, and the disk I/O has already started to fall to zero around 10 AM. Participants started coming in around 9:45 AM. I am unable to figure out what the reason might be. I was able to access my meet website from Chrome (but was very very laggy) but even that wasn’t possible from firefox.
Let me know if you need more information. Thanks.
