Hello everyone,
I've rebased the experimental branch again with my latest performance
fixes.
I took out the delayed unlink code, it wasn't making a big enough
difference in any benchmarks to justify the complexity.
I changed the delayed backref code to do delayed processing for all
extents. In general it is much faster and uses less stack.
I pulled Josef's enospc work into the master branch and asked Linus to
pull it.
I'm going to hammer on the experimental branch for a few days and ask
Steve to give it another run.
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.
Steve
