Subject: [PATCH] ext4: Speedup WB_SYNC_ALL pass
Date: Fri, 10 Oct 2014 16:23:20 +0200 [thread overview]
Message-ID: <1412951028-4085-16-git-send-email-jack@suse.cz> (raw)
In-Reply-To: <1412951028-4085-1-git-send-email-jack@suse.cz>
When doing filesystem wide sync, there's no need to force transaction
commit (or synchronously write inode buffer) separately for each inode
because ext4_sync_fs() takes care of forcing commit at the end (VFS
takes care of flushing buffer cache, respectively). Most of the time
this slowness doesn't manifest because previous WB_SYNC_NONE writeback
doesn't leave much to write but when there are processes aggressively
creating new files and several filesystems to sync, the sync slowness
can be noticeable. In the following test script sync(1) takes around 6
minutes when there are two ext4 filesystems mounted on a standard SATA
drive. After this patch sync takes a couple of seconds so we have about
two orders of magnitude improvement.
