RPM Builds and System Optimization

[David Cary Hart]

Most of the Fedora RPMS are provided as i386. These can easily be
recompiled as:

rpmbuild --target i686 --rebuild package.src.rpm

a. Is it worth it? In other words, is there really a performance gain in
packages like - say - KDE?

b. Assuming that I installed the RPM sources and built from the spec
file, as long as I am at it, could I also benefit by changing some of
the FLAGS?

	For example:
		CHOST="i686-pc-linux-gnu"
		CFLAGS="-march=pentium4 -O3 -pipe -fomit-frame-pointer"
