* 40 User: 16% CPU-Auslasting auf Xeon(R) CPU E3-1275 v5 @ 3.60GHz, 80MBit/s eingehend, 30 MBit/s ausgehend
At line 325 added 33 lines
Der "Stress-Level" eine einheitenlose Kennzahl, standardmäßig auf 50000pps (eingehend+ausgehend) normiert. Als Beispiel: Wenn die Video-Node 10000pps eingehend und 10000pps ausgehend hat, dann ergibt das 20000pps / 50000pps = 0.4, also einen "Stress-Level" von 0.4 oder 40%.
Kalibrierung des Stress-Berechnung an vorhandene Hardware. Dazu einmal eine "große" Konferenz, zB mit 15 Personen starten, dabei die Paket-Rate (pps) und CPU-Auslastung erfassen.
Als Beispiel: 25000pps auf 8-Core Intel(R) Xeon(R) CPU E3-1275 v5 @ 3.60GHz führten zu 16% CPU-Auslastung. Annahme: Bis zu 80% CPU ist ok, dann heißt das geschätzt 80%/16% = 5 * 25000pps = 125000pps als Lastgrenze:
In {{{/etc/jitsi/videobridge/jvb.conf}}} das Ergebnis eintragen:
{{{

# Whether or not the reducer will be enabled to take actions to mitigate load
