Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG I did a small test today to try test the speed impact of the KSE test. during this, I noticed that soft updates is not having it's usual performance increaseing effect.. Normal kernel, soft updates: 1387.881u 603.392s 35:48.63 92.6% 2694+2248k 12424+3310io 3587pf+0w KSE kernel, soft updates: 1385.979u 605.575s 35:21.41 93.8% 2695+2252k 11558+3300io 3705pf+0w Normal kernel, NO softupdates: 1389.803u 594.961s 35:59.14 91.9% 2697+2248k 11839+66940io 3701pf+0w It's interesting that despite the the extra writes (63640 of them) it took almost the same time from all metrics. this is a 35 minute subsection of buildworld.. i.e. buildworld up to a particular point, there may not be anything wrong but I expected more improvement. I remember that when I first committed softupdates it made a noticable difference.... To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
