If you don't feel it is enough, then use a custom scan and bump up the volume.
I honestly haven't seen any appreciable/noticeable difference from the last pre-release version. But I don't have large media stores and I don't have a lot of data on my system. Quick scan just took 3.00 minutes for only 4.9GB and if anything that is much slower that with the last 6.0.1125/1184 builds. But it is hard to say as I don't know if on the new program update any persistent cache is rebuilt.
Running the Quick scan right away does make a difference, 2:18 minutes for 4.9GB. Which is pretty much back where the previous builds were.
