I originally reported it to the CentOS Infra tracker [0] but was advised to post it here, since this behavior is, for better or worse, expected, or at least that's how the T2 machines are advertised. Is there anything that can be done to mitigate this? The only available solution would be to move the job back to the metal nodes, but that's going against the original issue (and the metal pool is quite limited anyway).
T2 instances don't have to be rate limited if you are ready to pay for it: iiuc the T2 unlimited mode [1] allows you to trade higher CPU utilization for money.
Cheers
Michael
