0% of swap used is generally a "good thing".  It means there is zero
paging to and from disk which likely means your workload is not taxing
the virtual memory system at all.  Using swap does not reduce the load
on the CPU.  If anything paging to and from swap will increase your CPU
load, since it takes some cpu time to run the paging algorithm.
