machine sizes vs machine counts

[njharter]

Investigate if Caduceus can push more messages is smaller machines and more of them.

so if current machines are:
8 cpu, 16 ram
54 machines

change it to:
4 cpu, 8 ram
108 machines

will this cluster perform better?

Given SNS limitations, I don't think we can reasonably double our caduceus machines because it will double the SNS transactions and we could hit limits.

Edit: talked with Nick and this only affects how quickly we could bring up caduceuses, but we can still have more of them.
