Mesa does not enable compiler optimisations by default:
http://cvs.freedesktop.org/mesa/Mesa/configs/linux-dri (see the log next 
to the 1.12 revision)
http://sourceforge.net/mailarchive/forum.php?thread_id=5432450&forum_id=5154

I spotted this when I was testing modular X.Org X11 in September 2005. I 
also wrote an email about it to Mike A. Harris , but I did not get an 
answer ;)

Mesa seems to be built with `-Wall -O -g' flags. You may want to 
download srpm and modify configs/default/linux-dri file. Changing 
OPT_FLAGS variable to the output of `rpm --eval %{optflags}' command may 
resolve your problem.

Unfortunately, I cannot test it because I have nVidia crap and nv driver 
does not support 3D acceleration [1]. Hopefully, I'll swith soon to ATI 
RADEON 8500 :)

[1] It would be great if someone could port BeOS driver to X.Org X11
