G1NewSizePercent is too coarse on very large heaps

    Details

    • Subcomponent:
      gc

      Description

      G1NewSizePercent is used to specify the minimum young gen size as percentage of the total heap. It is a percentage, i.e valid values range from 0 to 100.

      For large heaps (>100G) this can be too coarse: even specifying one percent may specify a minimum young gen size that makes it very hard to reach small pause time goals, particularly for mixed collections.

      Try to come up with some way to lift this restriction.
