Subject: [PATCH RFC 0/3] NFS41: optimize layoutget
Date: Wed, 8 Aug 2012 10:03:09 +0800 [thread overview]
Message-ID: <1344391392-1948-1-git-send-email-bergwolf@gmail.com> (raw)
The patches optimize layoutget size by sending real IO size instead
of just a small length in each layoutget. It helps server to do better
decisions about layout segment size and thus helps reduce layoutget
operation numbers a lot.
Boaz please see if you like the behavior in generic layout. If not, I can
make it block layout only.
Thanks,
Tao
