Does systemd on RHEL7 contains support for the CPUQuota (cpu.cfs_quota_us) to assign a CPU time quota?

Solution Unverified - Updated -

Issue

  • We are building a rhel7 baseline and we see a problem.
  • In RHEL6 we use cgroups with CPUQuota (cpu.cfs_quota_us ) to limit CPU processes.
  • We use CPUQuota for all our management processes (cfengine / nagios / tivoli / etc.) and have just chosen CPUQuota not to disturb other processes.
  • When measuring after using CPUQuota the improvement was detectable.
  • We want to also use RHEL7 with systemd. But this is not available in RHEL7 with systemd version 208. It was introduced in systemd version 213.

Environment

  • Red Hat Enterprise Linux (RHEL) 7
  • System and Service Manager (systemd) 208
