    Description

      Currently plasma mem tuner logic decrements memory quota and forces GC when the indexer process RSS overshoots user quota by 15% but the increment logic does not examine RSS before choosing to restore the quota.

      This results in spiky RSS and frequent forced garbage collection.

      Better to use examine RSS and only increment if the RSS is below user quota.

      Inspiration: PID controller
