CMS/G1: gc pause latency/scalability concern for flushing deferred card marks single-threaded

    XMLWordPrintable

    Details

    • Subcomponent:
      gc
    • CPU:
      generic
    • OS:
      generic

      Description

      The fix for 6896647 moves the deferred card-mark flushing into the single-threaded prologue of GC, which can theoreticaly at least be a bottleneck to GC pause latency scalability and cause the occasional long GC pause. This can be addressed by means of GC recognizing the deferred card marks as a special modified reference set, amenable to parallel and concurrent processing.
