Hello, Dan: I've known your md(raid456) patch just before v2.6.26, http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=8b3e6cdc53b7f29f7026955d6cb6902a49322a15 your md patch referred to tiobench, which is the multi-thread benchmark tool, I'm interested on this tool and I found I ran it differently with your results, so I want to know more about it, from its home page, it only released v0.3.3 on Mar 2002, http://sourceforge.net/projects/tiobench/ but from its cvs repository, it has released v0.4.1, http://tiobench.cvs.sourceforge.net/tiobench/tiobench/ Could you tell me what version of tiobench did you use? I want to see if that's my configuration fault or I have used wrong program version. And when using v0.4.1 of tiobench from its cvs repository, I found its multiple threads random IO statistics code reported wrong results, and have resolved it by this patch, http://sourceforge.net/tracker/index.php?func=detail&aid=2047536&group_id=3857&atid=303857 But its upstream seems have not noticed it yet, so I want to if someone on this mailling-list know tiobench upstream and be able to take this message? Thanks. -- Denis Cheng -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
