Switch from openjdk:8u212-jre-alpine3.9 to openjdk:11-jre-slim-buster .

OpenJDK 11 performs better with the G1 default garbage collector than OpenJDK 8.

Seems OpenJDK 11 is a lot faster than 8 (due to G1 performance?).

Some details:

  • FSImage : 7 GiB / 12m dirs / 70m files
  • Configuration with
  • Same JVM options (-server -Xmx12g -XX:+UseG1GC)
  • OpenJDK 8u262 : 350s
  • OpenJDK 11.0.8 : 110s (!!!)
  • Repeated/reproduced 3x
