CPU cores on KVM VPS are shared among multiple VPSs. If your VPS is consistently maxing out one full core or more and impacting the performance of other client servers sharing the same host node, we may ask you to reduce your usage. Disruptive load may result in a reboot, shutdown, and/or suspension of the VPS regardless of the time lapse involved. 30% Average Usage should be fine. You can burst up to 100% for 10 minutes, every 24 hours.
