    Haven't got taken down by a SlashDot in about a year... I am not worried at all. In recent months the servers (and the Phoronix Content Management System) have handled Digg, SlashDot, Engadget, etc fine Heck Phoronix has had 60+ Digg front-pages, and I think only on three or four cases did it bring the server down.

    The SPECViewperf 9.0.3 results for Solaris Express Developer
    Edition 1/08 are low for two reasons.

    First, when adding xVM dom0 support to the NVIDIA graphics
    driver I broke a path in the kernel driver which optimizes
    OpenGL performance. This is being tracked under Sun bug:

    6665672: fix for 6593812 causes OpenGL performance regression

    This will be fixed in Solaris Express Community Edition
    build 85.


    Second, to clarify an earlier comment by elvis, while the
    SPECViewperf 9.0.3 benchmark is single threaded, OpenGL itself
    has MT support. (See section 3.7 of the OpenGL ABI for Linux).
    The Linux driver runs in single thread mode if it does not
    detect the application was built with -lpthread. Solaris
    has a unified thread model which forces the driver into
    thread safe mode by default. Since Viewperf 9.0.3 is compiled
    without -lpthread, by default it runs in faster single thread
    mode on Linux and thread safe mode on Solaris. To run
    Viewperf 9.0.3 equivalent to Linux single threaded mode,
    set the environment variable:

    export __GL_SINGLE_THREADED=1

    I don't expect this issue will ever be "fixed".

    Heh... I'd not get my server plant taken down, but I'd sure as heck have the pipe choked off if I got a good old-fashioned Slashdotting.
