I'm running into this. I have a server that can handle way more than 16 vCPUs. I know this topic has been talked about several times, and theoretical discussions keep taking place. A bit more than two years later, and this is still a topic of discussion. I'm curious if anyone has a patch to punish me with. I'm very happy to be a guinea pig.
