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?
