If you install glibc i686 then most of your programs will be running a
lot of i686 optimized code, even if compiled on normal i386
optimizations, because they usually use most of their functionality
derived from glibc'shared libraries.

The same applies to everything else, so the speed bump should not be
very significant (although perhaps noticeable, I don't know).

However, noarch rpms are usually TEXT scripts that are interpreted by
some program (perl, python, shell, whatever) and will result in no
optimization whatsoever if compiled for i686 (if they even accept to
build).
