Faster? If you had a really old version I guess there could be a lot of fixes from the master branch that are incorporated, I summarized those in the first post. But, I think we pushed that out around January already. The master branch hasn't changed since then, so all the changes since January are mine, and I think the only thing I fixed was the new power kernel v47 temperature and voltage readings, and getting lua, cairo, and curl enabled. Those should really slow it down if anything :P
Maybe your conf file got updated, or it's not really faster, otherwise I can't explain it.
