Done.  Results for RAID are updated in history tree   
http://btrfs.boxacle.net/repository/raid/history/History.html

This gives back a few of the performance improvements made on the tree 
from the 24th (mail server and random write).

Also, I have reordered the bars with btrfs at the end for 2 reasons. 
First, makes it a little easier to find the latest btrfs results.  Also 
this fixes a problem with my scripts where I was not picking up the 
random write odirect tests.

Single disk tests are running.
