Normalize PAWS resource usage
Closed, ResolvedPublic


A brief snapshot of PAWS usage shows worker cpu as less than 10% and memory as more than 60%. All of the worker systems are running a flavor that has 1 cpu to 2G ram, we can probably improve this by using a 1:4 flavor, and putting out half the number of cores (down to 22 worker cpu from 44). This should likely only be done as part of/after moving to magnum T308873.
