Subject [jira] Commented: (LUCENE-2662) BytesHash
Date Fri, 01 Oct 2010 17:36:34 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12916965#action_12916965

Michael McCandless commented on LUCENE-2662:
--------------------------------------------

I also ran a test w/ 5 threads -- they are close (22,402 docs/sec for patch, 22,868 docs/sec
for trunk), and this time avgUsedMem is closer (811 MB for trunk, 965 MB for patch).

I don't think the avgUsedMem is that meaningful -- it takes the max of Runtime.totalMemory()
- Runtime.freeMemory() (which includes garbage I think), after each completed task, and then
averages across all tasks.  In my case I think it's averaging 1 measure per thread, so it's
really sort of measuring how much garbage there happened to be at the time.
