[...] Do I understand correctly that you are comparing the speed of software rendering with a distribution-built Mesa and your own build, and that you are not interested in pass-through (i.e. hardware accelerated on the host) here? If so then you are probably better asking the people who built the distribution package.
To my knowledge, the Gallium on LLVM renderer is software-only, though many open source GPU drivers do make use of LLVM (ours doesn't). Regards, Michael -- ORACLE Deutschland B.V. & Co.
