I am referring to this thread: http://www.nabble.com/Red5-and-Multicore-proccessor-to12897110.html#a12897110
My system has a quadcore cpu and I am observing the following using top: A lot of processes are in the process list multiple times like events/0, events1, events/2, events/3. As far as I know this is one process for each core.
Now my red5-java process is in that list only once with name java. The CPU utilization of that single process is quite high, spiking up to 40 even 70 percent while the overall cpu utilization is low at about 6%-12%.
Now I wonder what does this mean? Is the java thread running only on one core with high utilization instead of using all cores?
How can I make sure that the jvm is using all multicore capabilities and utilizing each core?
I would love to see the process like java/0, java/1, java/2, java/3. Is there any setting withing red5, jvm or the os to do that or to make sure it uses all cores?
