Hi Palash

The CPU in Mhz is a bit of a misnomer as it doesn't really relate to the actual 
CPU speed. It is used more as a CPU 'weight' and we set our value to '1' and 
then hide the 'CPU in MHZ' from the UI. It also relates to how CGroups on the 
underlying hypervisor are configured and in our case - Ubuntu 20.04 there is a 
hard coded value in libvirt so when we had a Compute offering with say 24 cores 
at 2000 MHZ we found we could no longer deploy more VM's using this compute 
offering once the libvirt cgroup limit was reached. It gets even worse in 
Ubuntu 22.04 as the hard coded libvirt cgroup value is much less.
All of our running VM's still show the actual CPU speed in terms of Ghz when 
using compute offerings with a value of just 1 Mhz

Subject: Question on Compute Offerings.

Hi Community,

Question on Compute Offerings.

- In the 'CPU (in MHZ)' section, does we put in the Base Clock Speed? Or the 
Max Clock speed of the CPU? |
- Is the 'Network Rate (Mb/s) Parameter restrict only internet bandwidth?
Or does it also include traffic via Private Gateway (maybe to another
datacenter)

Thank You
