Re: [Mesa3d-dev] mesa solo slower than with X

[Jon S. <jon...@ya...>]

Mesa-solo does not build with x86 asm turned on and DRI is using x86 asm. It
shouldn't be too hard to make a linux-solo-x86 target.

DRI also includes:
-DUSE_X86_ASM -DUSE_MMX_ASM -DUSE_3DNOW_ASM -DUSE_SSE_ASM 

I also believe mesa-solo defaults to debug optimizations.

If you get all of the compiler options set the same they should have the same
performance, after all they are generated from the same code. Try putting
together a linux-solo-x86 target with full optimizations.
