If you feel adventurous, you could try my reverse mapping VM: http://surriel.com/patches/2.4/2.4.17-rmap-12f The changelog can be found at http://surriel.com/patches/Changelog.rmap kind regards, Rik -- "Linux holds advantages over the single-vendor commercial OS" -- Microsoft's "Competing with Linux" document http://www.surriel.com/ http://distro.conectiva.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

The -rmap (reverse mapping) VM is an attempt to fix some of the fundamental virtual memory management problems that have plagued Linux since its introduction to larger machines and more complex workloads. It is an attempt at a more flexible and robust VM. While little performance tuning and optimisation has been done yet, people have found it to perform better than the standard VM for various workloads. This version of the kernel RPM with -rmap VM is based on 2.4.18 as shipped by Conectiva and the latest stable -rmap version 12 VM. These kernel RPMS, with stable -rmap VM, are available from: http://nl.linux.org/pub/linux/conectiva/kernel-rmap/ ftp://nl.linux.org/pub/linux/conectiva/kernel-rmap/ More experimental versions of the -rmap VM can be found on: http://surriel.com/patches/ http://linuxvm.bkbit.net/ kind regards, Rik -- <insert bitkeeper endorsement here> http://www.surriel.com/ http://distro.conectiva.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
