Re: Ignite WebSessionFilter client threads eating up CPU usage
After we switched build-in openJDK (jdk-8u181-ojdkbuild-linux-x64) to Zulu JDK (zulu18.104.22.168-ca-jdk8.0.212-linux_x64), it still has a high loading CPU usage.
And we found the linux node has a low CPU frequency than other nodes w/ same configurations on CentOS 7.5.
Finally, we correct the CPU frequency with
cpupower idle-set -d 0 #1 2 3 4 5 6
cpupower frequency-set -g performance.
The high CPU loading situation is getting well.
So, this check could be a first check while system tuning.
using a supported JDK.
Thank you all!
