G1: Improve cpu usage measurements for heap sizing

XMLWordPrintable

    • gc
    • b13

      Currently G1 only uses pause times as a metric to calculate the gc cpu usage.

      This disregards concurrent cpu usage completely.

      Make the calculation more accurate; this might require retuning of `GCTimeRatio`.

      Some platforms may not support more exact CPU measurements so the current mechanism might need to be kept.
