I've spent *considerable time* keeping fully optimized i686 mtune p4 -O3 
compiled gentoo installed on a machine I also had Fedora rawhide with *my own 
compiled and optimized i686 kernel and glibc*... the differences are minor at 
best.  I guarantee a i586 compiled SUSE install is not faster than that gentoo 
build.

If you're really seeing that large a performance difference you need to be 
considering legitimate sources of 'startup' time, such as already mentioned in 
the thread... disk IO.  How SUSE is choosing to link the libraries might be the 
place to start.  Are they prelinking?  How.  Did they maybe statically link 
certain apps (like firefox that is used more than anything else)?
