             Bug #: 42117
           Summary: r200 driver performance, ums, all mesa versions from
                    7.6
    Classification: Unclassified
           Product: Mesa
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/DRI/r200
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: majkell10 at interia.pl


With disabled ModeSetting, performance in some 3d applications drop almost to
zero.

glxgears runs flawlessly,
few maps in openarena is unplayable,
extremetuxracer is unplayable.

oprofile with tuxracer:
CPU: Athlon, speed 1399.45 MHz (estimated)
Counted CPU_CLK_UNHALTED events (Cycles outside of halt state) with a unit mask
of 0x00 (No unit mask) count 100000
samples  %        symbol name

21567     2.4631  radeonReadRGBASpan_ARGB8888
11802     1.3479  radeonWriteRGBASpan_ARGB8888

I've tested almost all mesa versions from 7.6 to 7.11, unsuccessfully. With
mesa 7.5 all works great. Mesa 7.6.1 compiled with folders radeon and r200
copied from 7.5.2, also works great.
