Hello @damencho, @bbaldino and all others.
I’m looking for where the problem might be. We have enough system resources and yet we have a high load. If the load is higher than 4.9, the audio and video will start fails. This is the default installation of jitsi - unmodified on Debian 9.12.
Every participant has their cameras on. We have an average of 8 conferences, with a maximum of 20 participants. Low data flow is due to verry reduced resolution / video quality.
Can I ask for advice on how to reduce the server load ? We have enough system resources and I don’t think it is necessary to install a second video-bridge2.
Hum, it looks to me strange where CPU is 20% and load is above 4 …
Do you see which process is eating the CPU?
@damencho Thanks for every idea what I could try. @migo has similar problems, but he has a larger installation than me.
I agree with damyan that low CPU but high load is strange, I don’t think that’s a behavior we’ve seen. Maybe lots of threads are getting held up blocking somewhere? You could do a YourKit trace or something and see what the threads are doing.
@bbaldino Please can you help or navigate me how ? Alternatively, can you send me your ssh key ? I can give you ssh access to the server…
This is from today morning.
Any idea ?
Looks pretty well. Load is 0.7 out of 24. And cpu for the whole machine is 6%.
why the java JVB is consuming 147% ?
because it’s actually doing work.
1.6 core (1.47 + the few remaining processes doing work) / 24 cores = 0.0666 == 6,66% cpu usage
For my clarification:
jvb uses several cores aka multithreading?
While I have never checked the ultimate reference - the source code - I think that looking at the htop output leaves no real doubt that the answer is yes.
