G1 creates too many concurrent refinement threads by default

XMLWordPrintable

    • gc

      Ever since Concurrent Refinement was parallelized (JDK-6484957), the number of threads created by default (G1ConcRefinementThreads) has been equal to ParallelGCThreads.

      I think by default we should scale G1ConcRefinementThreads down by about the same amount as ConcGCThreads are scaled down. On the linux box I'm using this would reduce G1ConcRefinementThreads from 13 down to 2.
