commit 3575109bebf4269c1fd02550b6bf9580f92b0ef4
Author: Joachim Breitner <mail at joachim-breitner.de>
Date:   Mon Oct 13 16:37:15 2014 +0200

    Update more performance numbers due to stricter seqDmdType
    
    including T9675 itself. Maybe its memory behaviour is too spiky for
    max_bytes_used and peak_megabytes_allocated to be used sensibly at all.
