The following patchset brings one more batch of performance improvements
with dbench workloads, or anything that mixes file creation, file writes,
renames, unlinks, etc with fsync like dbench does. This patchset is mostly
based on avoiding logging directory inodes multiple times when not necessary,
falling back to transaction commits less frequently and often waiting less
time for transaction commits to complete. Performance results are listed in
the change log of the last patch, but in short, I've experienced a reduction
of maximum latency up to about -40% and throuhput gains up to about +6%.
Filipe Manana (7):
btrfs: remove unnecessary directory inode item update when deleting dir entry
btrfs: stop setting nbytes when filling inode item for logging
btrfs: avoid logging new ancestor inodes when logging new inode
btrfs: skip logging directories already logged when logging all parents
btrfs: skip logging inodes already logged when logging new entries
btrfs: remove unnecessary check_parent_dirs_for_sync()
btrfs: make concurrent fsyncs wait less when waiting for a transaction commit
