Subject [jira] Commented: (HARMONY-5703) [drlvm][performance] j.l.ThreadLocal performance optimization
Date Thu, 05 Jun 2008 23:22:45 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-5703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12602850#action_12602850
] 

Aleksey Shipilev commented on HARMONY-5703:
-------------------------------------------

The draft patch running on Harmony/DRLVM gives 7.6x speedup on MTHarness/ThreadLocalBench
while running on 2-core Core2Duo.
Still, Harmony/DRLVM is ~3x slower than RI, presumably connected with codegeneration issues.
