Subject: Re: Block IO Controller V4
Date: Tue, 08 Dec 2009 10:17:48 -0500	[thread overview]
Message-ID: <1260285468.6686.12.camel@cail> (raw)

Hi Vivek - 

Sorry, I've been off doing other work and haven't had time to follow up
on this (until recently). I have runs based upon Jens' for-2.6.33 tree
as of commit 0d99519efef15fd0cf84a849492c7b1deee1e4b7 and your V4 patch
sequence (the refresh patch you sent me on 3 December 2009). I _think_
things look pretty darn good. There are three modes compared:

(1) base - just Jens' for-2.6.33 tree, not patched.
(2) i1,s8 - Your patches added and slice_idle set to 8 (default)
(3) i1,s0 - Your patched added and slice_idle set to 0

I did both synchronous and asynchronous runs, direct I/Os in both case,
random and sequential, with reads, writes and 80%/20% read/write cases.
The results are in throughput (as reported by fio). The first table
shows overall test results, the other tables show breakdowns per cgroup
(disk).

Regards,
Alan
