It's interesting that the RAM/CPU ratio is about double the default shapes from AWS/GCP. In practice I have generally seen those shapes run on the low side of CPU utilization for most workloads, so I think the choice makes sense. I'm curious if ARC will be running with primarycache=metadata to rely on low latency storage and in-VM cache, otherwise I could see ARC using a fair bit of that RAM overhead in the hosts.
