We're in the process of moving from Ubuntu to CentOS 7, with which I am largely unfamiliar. We're not in the finance sector, but latency does matter in our systems (probably not so much as it matters to the HFT people, though). Can anyone tell me whether this guidance for RHEL 7 is likely to apply to CentOS 7? |

Although some of the tuning there-in can be used for improving performance on any workload (handling NUMA, for example), it's probably not necessary for the majority of environments because it involves intimate knowledge of hardware, software and application stack.
It also talks about disabling a bunch of power management which is really only necessary when you're chasing microseconds.
BTW if you're interested in NUMA and memory management on RHEL7, my team mate Bill Gray wrote an awesome whitepaper:

OP: please consider RHEL :-)
