Winner!  Both of those settings were set to always, and as soon as I turned them off, the query times smoothed right out. 

Thank you all so much for your help!

Scott, 

Is transparent huge pages turned off along with defrag?  Check 

/sys/kernel/mm/transparent_hugepage/enabled
and
/sys/kernel/mm/transparent_hugepage/defrag
Both should be configured with "never".
