Subject [jira] [Commented] (HBASE-5699) Run with > 1 WAL in HRegionServer
Date Mon, 15 Dec 2014 19:09:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14247057#comment-14247057

Jonathan Hsieh commented on HBASE-5699:
---------------------------------------

I like the new graph -- summarizes a lot and is still simple to follow.

I'm trying to make sense of the 20-25% boost (hoped for more!).  These are 5 disk machines
-- are these boxes configured so that one disk per machine set aside for the os and 4 disks
are "data" drives?
