Except that's not quite true either. Part of the depsolving is done with 
rpmlib calls: yum loads rpm headers into a transaction and gets lists of 
missing dependencies, looking for packages providing those dependencies 
is done by yum itself.

In FC6 the hideous yum slowdown comes largely from reopening the rpmdb 
literally hundreds of times. Check out 
https://lists.dulug.duke.edu/pipermail/yum-devel/2006-November/002870.html 
for some metrics. Yum 3.0.1 isn't *that* bad, but 3.0 is dog slow whereas 
2.9.6 was lightning fast.
