Red Hat engineers this weekend released Tuned 2.27, the newest version of their open-source project to provide a tuning profile delivery mechanism for Linux. Tuned makes it easier to adjust Linux power and performance characteristics depending upon the hardware and the different workload(s) for your Linux system deployment. Tuned is a replacement/alternative to Linux's cpupower and power-profiles-daemon utilities.

Red Hat's Tuned 2.27 brings CPU partitioning improvements, optimizing TCP settings for high throughput and low latency when running OpenShift, setting the CPU boost option in the performance profiles, adjusting latency for SAP HANA, and other updates.

- cpu-partitioning: autodetect dracut hook directory, systemd workaround

- openshift: optimize TCP settings for high throughput and low latency

- profiles: Set boost=1 in *-performance profiles

- sap-hana: force latency to 70 us, not to C-states

- man: fixed instance_acquire_devices example in tuned-adm man

- spec: use correct python interpreter for documentation installation

- sysctl: add reapply_sysctl_exclude option

- ppd: ask tuned recommend for base profile

Those wanting to try Tuned 2.27 for tuning your Linux systems/servers can find the new release via [1]GitHub .
