We have set up a new page which is intended mainly for tracking the

here might find the results useful.
I think I understand the bad read performance in btrfs. I was forcing a
tiny max readahead size.
The current git tree has fixes for it, along with a ton of new code.
Ok, we'll kick off some new runs.
Also, just need to push out the data fro odirect random write and mail
server with fsync.

We have completed testing on the random write tests with odirect.
Results can be found at:
Single disk:

Raid:

Also, the changes to the mail server emulation to use fsync on the
creates is also complete:
