Subject [jira] Updated: (HBASE-1387) Before release verify all object sizes using Ryans' instrumented JVM trick
Date Fri, 19 Jun 2009 21:34:09 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1387?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Erik Holstad updated HBASE-1387:
--------------------------------

    Attachment: HBASE-1387-v5.patch

Reworked some of the heapsize calculations to better fit the actual memory used. 
Have been comparing to the numbers given by, the great help tool SizeOf(http://sizeof.sourceforge.net/).
To get SizeOf going in Eclipse you need to do :
run as, open Run Dialog and add -javaagent:path/SizeOf.jar to the VM arguments window.
