> The vcores-pcores ratio functions differently from the vmem-pmem ratio in the sense that
the vcores-pcores ratio has an impact on allocations and the vmem-pmem ratio does not.
> If I double my vmem-pmem ratio, the only change that occurs is that my containers, after
being scheduled, are less likely to be killed for using too much virtual memory.  But if I
double my vcore-pcore ratio, my nodes will appear to the ResourceManager to contain double
the amount of CPU space, which will affect scheduling decisions.
> The lack of consistency will exacerbate the already difficult problem of resource configuration.
