How does VPS CPU upper limit in MHz resource type limit work?

Resolution

VPS CPU upper limit in MHz is converted into CPU Limit proportionally to the CPU core power available on the target hardware node.

Example:

VPS subscription is configured with

VPS CPU upper limit in MHz = 2000 VPS CPUs = 1

The hardware node, where VPS has been provisioned, has:

[root@vz ~]$ cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 58
model name      : Intel(R) Xeon(R) CPU E3-1230 V2 @ 3.30GHz
stepping        : 9
cpu MHz         : 3301.000

In this case the VPS will be assigned 1 CPUs with CPULimit = 60% = (2000 / 3300) * 100%
