Liquibase 2.0 slower than 1.9?

I've just upgraded to Liquibase 2.0.2 using the provided jar file, and I've found that it runs slower than its predecessor. If no updates are necessary, it still takes about 15 seconds to run, compared to the <5 it took before. I've updated the xsd formats as well.

I'm just wondering if anyone else has encountered this, as I'm afraid to see how long it will take when it has to do real updates to our production environment. Thanks.

Here is a log with some simple updates:
