pup and pirut is created  to be simple, if you want more options and 
output the try out yumex.
You can get the the latest development 1.9.x prerelease here:
http://www.yum-extender.org/dnl/yumex/devel/

or you can use the 1.2.x one currently in Extras.

Yum only download the header part of the rpm files from the mirror to 
feed it into rpm api, which does part of the depsolving.
I dont speed up thing to split out the header data into seperate files, 
like earlier versions of yum did, the same number of bytes have to
be download any way. Depsolving is a  complex task an it takes time to 
do, i prefere good depsolving, more than fast depsolving.
