Hi Justin, we've tried by turning off tls. It doesn't change: cpu usage remain very high. We've tried also by disabling persistence. It changes a bit: at the beginning of the connection phase, cpu goes to 50% ...then it increases time by time til it reaches 100% when there are about 1000 connected clients. Now we're going to add some logs to our scecurity plugin, to see the cpu consumption for every involved thread. Meanwhile I'm going to install and use Sun Oracle JDK 8, instead of the current OpenJDK 8, but simply to have jmap, jstack and jcmd utilities to make some additional analysis (I can't find them inside the standard OpenJDK package for Centos7).
I'll let you know for further results. Of course, any suggestion to make a better performance analysis is appreciated. Thanks a lot.
