PS GC is too slow in fastdebug

    Details

    • Subcomponent:
      gc
    • CPU:
      x86
    • OS:
      generic

      Description

      Tests
      vm/oom/limit/OOMLimitTrace_charArr
      vm/oom/limit/OOMLimitTrace_shortArr
      run really slow in fastdebug on sparc with huge memory.

      The GC of 4 G (young space) takes about 10 minutes.

      However all works fine in product or with other collectors (Serial, G1)

      To reproduce on vm-t5440-01b:
      export CLASSPATH=/net/sqenfs-1.sfbay/export1/comp/vm/testbase/sqe/vm/7/build/execution/vm/bin/classes
      /net/sqenfs-1.sfbay/export1/comp/vm/jdk/hsx/hs20/pit/06/jdk7b125/fastdebug/solaris-sparcv9/bin/java -d64 -XX:+PrintGC -server -Xmixed -XX:+StartAttachListener vm.oom.limit.OOMLimitTraceTest -gp charArr -iterations 3

      Tail of log:
      [2011-01-11T20:32:33.03] # Test level exit status: 151
      [2011-01-11T20:32:33.83] # Host info: SunOS vm-t5440-01b 5.10 Generic_142900-12 sun4v sparc SUNW,T5440
