G1 before/after GC time graph
Hi,

There was talk of G1 and HBase here over the past few days.  I wanted
to share a fresh and telling SPM graph showing G1 + some other params
in action:

Result first: https://apps.sematext.com/spm/s/wN0hKVixxX

This is what we had before:
  -XX:+HeapDumpOnOutOfMemoryError -XX:+UseG1GC
-XX:InitiatingHeapOccupancyPercent=35 -XX:G1ReservePercent=25

And then we added:
  -XX:MaxGCPauseMillis=200 -XX:NewRatio=4

I hope this helps.

Otis
