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. > Check out the numbers on the cElementTree webpage.
