Why pcStatsInterval is used?

I have been investigating parameters in config.js file, and I wonder why pcStatsInterval is neccessary?
What kind of feature is disabled when I completely disabled the pcStatsInterval parameter?

Besides that
I realized that default value of pcStatsInterval is 10seconds, every 10 seconds a participant sends his own stats to the JVB, and this stats have been broadcasted by JVB to all other participants.
I wonder why broadcasting is performed?


Probably jvb use this stats to calculate bandwidth allocation. But do clients need to send this message as broadcast message?

When we do load testing, we see significantly high stats messaging which may effect large room performans.

Gsm bars info messages … they are not used for bandwidth allocation.
That’s why by default those are every 10 or 20 seconds …
