    Default Bandwidth Benchmark

    How long does this bench take to usually run? Going on 20 minutes now and counting.

    Well I have got already a patch that would allow to use options to the benchmark tool to only run the used benchmark not all, just did not integrate it into pts yet. The runtime is pretty annoying currently.

    OK so this is expected currently then and not abnormal? It seems like it never gets past testing the "Framebuffer memory sequential read"

    That doesn't seem normal. What's your hw/sw configuration?

    System A

    OpenSUSE 11.0 daily build x86-64
    AMD 6400+
    Asus M2N-E Motherboard
    4 GB Ram
    Nvidia 8800 GT

    System B

    Bluewhite64 Linux 12.1-rc1 x86-64
    AMD 4200+
    Asus M2A VM HDMI
    2 GB Ram
    AMD x1250 integrated graphics

    System C

    AMD 3200+ Socket 754
    Asus K8N-E Deluxe

    All will sit forever when doing the Framebuffer memory sequential read and never complete.

    As in it's still taking you 20+ minutes to run Bandwidth?

    BTW I thought I would report that it does eventually complete as otherwise reported. It just takes an absurdly long amount of time (1hr plus)
