Subject: [patch] speed up ext3 synchronous mounts
Date: Sun, 24 Mar 2002 13:50:16 -0800	[thread overview]
Message-ID: <3C9E4A18.7DDC68AB@zip.com.au> (raw)


Again, we don't need to sync indirects as we dirty them because
we run a commit if IS_SYNC(inode) prior to returning to the
caller of write(2).

Writing a 10 meg file in 0.1 meg chunks is sped up by, err,
a factor of fifty.  That's a best case.
