           Summary: [r300g] slowdown with r300g threading
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: fabio.ped@libero.it


I noticed that since r300g threading was enabled many applications slowed down.
On setting RADEON_THREAD=0 openarena go from 94.9 to 100.0, glxgears (FWIW)
from 1275 to 1632.

Applications running under gdb shows hundreds of:

[New Thread 0xb6af3b70 (LWP 4622)]
[Thread 0xb6af3b70 (LWP 4622) exited]
[New Thread 0xb6af3b70 (LWP 4623)]
[Thread 0xb6af3b70 (LWP 4623) exited]

and slowdown even more (glxgears drop to ~100 FPS, supertuxkart drop by 50%).

I am running current mesa git + kernel 2.6.37.2 with a RV530 on an Intel Core
Duo.
