Hi
If you are looking for low latency in high percentiles for your thread pickup then I had good results with isolcpu.
How do you plan to setup cgroups to achieve the same “exclusive” core?
Cheers
Georges

Hello,--We are investigating the use of isolcpus and/or cgroups to isolate a set of cores where we will run our Java busy wait message processing threads (using a thread affinity library). Other threads will run on "generic cores".I think that we can achieve the same objective with both isolcpus and cgroups, and I was wondering if there are best approaches/shortcomings related to:- Using only isolcpus- Using only cgroups- Using isolcpus and cgroupsAlso, does the latest release of Red Hat 7 provides better support for cgroups versus isolcpus?Thanks for all your help/advise!Jean
