Raid FFSB Benchmark results for 2.6.35-rc5

Raid FFSB Benchmark results for 2.6.35-rc5

[Keith Mannthey]

This is a collection of benchmark runs with the FFSB test suite. The
results are comparable to other raid results on the boxacle server. 

The latest results can be found at: 
http://btrfs.boxacle.net/repository/raid/2.6.35-rc5/2.6.35-rc5/2.6.35-rc5.html

I added XFS without barriers and EXT3 with barriers into the mix since
my last data set. 

In general things look about the same.  There are a few cases where ext4
with barriers (default) has gotten better but ext4 without barriers has
gotten worse. 

Thanks,

Thanks, it's good to know there haven't been any major regression on
the ext4 side.

If you could have a chance to run a set of benchmark runs with the
jbd2 scalability patches, I'd be hugely interested to see how much
difference they make.

Thanks again!

Yes I am running with those today.  As the system is only a 16-way or so
it will be interesting to see the impact. 

I also have a few barrier reduction patchset test runs as well.  I will
work to put them all together and publish some ext4 only relevant run in
the next few days.  

Thanks,
  Keith
