Tune thread usage for concurrent tasks

    XMLWordPrintable

Details

    • gc

    Description

      Concurrent tasks often suffer from using too many threads because there is too little work available.

      Look at the various concurrent mark phases and see which of them can be easily automatically tuned to use a more optimal number of threads, and implement that.
