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.

Thanks,
