Message-ID: <252f133e0710300416x7490aeq4f371550fdf59b92@mail.gmail.com> Date: Tue, 30 Oct 2007 07:16:20 -0400 From: "Björn" <askadar@...il.com> To: linux-kernel@...r.kernel.org Subject: Huge performance regression in 2.6.23? Have a look at slides 17, 18, and 19 of the presentation available at http://people.freebsd.org/~kris/scaling/7.0%20Preview.pdf . It shows a huge drop in performance for both PostgreSQL and MySQL under 2.6.23. The slides are light on details on the exact setup, but I find it hard to believe that such a major regression would have gone unnoticed during testing of CFS. Maybe someone (with the appropriate hardware, which I lack) can try to reproduce the results? Is it really that bad? - Bjoern - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
