Big performance improvements seen with cifs async write patches evenover localhost

[Steve French]

Did some informal testing of Jeff Layton's cifs async_write patch set
tonight (recent kernel). Copying 700MB sequentially was 20% faster
from cifs kernel client to Samba 3.6 with his patches - even mounted
over localhost (where network latency is a much smaller issue) and
with a slow laptop drive!

I was simply doing

time dd if=/dev/zero of=/mnt/null bs=1M count=700

repeated 4 times each way (with old module, and with same code with
Jeff's cifs async write code builtin), deleting the target file in
between each run.

I am looking forward to trying this over GigE tomorrow to servers with
faster disks.
