These numbers smell very suspicious to me from my practical yum
experience but I never did any measurements so I cannot be sure.
But ever if they are correct this is really not the place where yum
is spending its time.  Running test transactions seems to be a big
time sink and dependency resolution as well.  In a comparison with
that shaving some few seconds on parsing, which is really not
noticable in the whole operation, sounds like a completely a
lopsided trade-off for one more extra XML parser and resulting
dependencies.

In the whole context?  I doubt it.  Unless you have some other
uses for that.
