Subject [jira] [Commented] (HBASE-9976) Don't create duplicated TableName objects
Date Fri, 15 Nov 2013 17:43:21 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9976?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13823846#comment-13823846
] 

Nicolas Liochon commented on HBASE-9976:
----------------------------------------

I had some performances issues when I push the client to something like 1.5 millions puts/sec,
as it adds a synchronization point. I need to do more tests around this.

> A profiling show that the table name is reponsible for 25% of the memory needed to keep
the region locations. As well, comparisons will be faster if two identical table names are
a single java object.
