 I'm sure solv files _could_ take 0.00001 instead of .sqlite's 0.01 to
do operations, I don't find that compelling though.

 If you want to say "yum sucks, zypper rules" feel free ... on your
blog.

 However, I do recommend you refrain from arguing that zypper converting
XML to solv files is faster than yum not doing any conversion ... it
seems less "I do bad benchmarks" and more "I'm insane", and even people
not familiar with yum can notice it.
 Really, you are disappointing us, we are used to much better
misinformation campaigns.
