[drlvm][gc]Significant performance degradation after switch on GC v5
--------------------------------------------------------------------

                 Key: HARMONY-3906
                 URL: https://issues.apache.org/jira/browse/HARMONY-3906
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Pavel Afremov


I found out significant performance degradation of class unloading support after switch on
GC v5. On 1 processor machine performance degradation in micro benchmark from HARMONY-3845
 can reach 10 times, on 4 HT processors degradation reaches up 80 times. It is 1000% and 8000%
correspondently!

 I developed additional benchmark, which shows this problem without any changes in VM. You
can find it in attachment.

 Of cause it's a synthetic benchmark. I didn't find any performance issues on specJVM and
specJBB.
