Some further testing in my case shows the issue is related to Java 8, 
because Java 7 does not show the slowdown.
I am still seeing the issue with Java 8u112 (which has several 
Sierra-related fixes in it).
Using h2 version 1.4.193 with url:
jdbc:h2:ssl://localhost:8955///Users/bob/path-to-my/db;MVCC=TRUE;MAX_COMPACT_TIME=5000;MV_STORE=FALSE
