Description Nathan Niesen CLA 2020-04-23 23:53:25 EDT 
Consider changing default memory settings to release unused heap after complex operations.

These settings work well with the existing `-XX:+UseG1GC` to release unused heap whenever the garbage collector runs.

-XX:MinHeapFreeRatio=30
-XX:MaxHeapFreeRatio=40
-XX:-ShrinkHeapInSteps

These are not overly aggressive and work well not only with the default heap settings but also with larger heap ranges like -Xms256m -Xmx8192m. This gives large operations the memory needed without permanently consuming it.
