    Description

      When -XX:+UseSerialGC is enabled, load the CDS archived heap objects into SerialHeap::old_gen() during VM bootstrap. This improves VM start-up time, mostly because the module graph can be loaded from the archive.

      $ perf stat -r 40 java -XX:+UseSerialGC -version

      Before: 0.042484507 seconds time elapsed ( +- 0.72% )
      After: 0.031671000 seconds time elapsed ( +- 0.72% )
