[Mesa-dev] glxgears is faster but 3D render is so slow

Well, the Xlib/swrast driver does everything in software, unlike a DRI
driver which does most things with the GPU. Xlib will always be slower.
The gallium llvmpipe driver should be quite a bit faster.
Just install LLVM first, then reconfigure/rebuild Mesa, set your
LD_LIBRARY_PATH to the lib/gallium/ directory and you should get llvmpipe.
