Persistent cache much improved in v. 6?

One nice feature of v.6, which I don’t recall seeing mentioned anywhere in the Avast website or here, is that if you’re set to use both caches, repopulating the persistent one from scratch (following uninstall and clean install) seems much faster now. Back when the cache was first introduced (ver. 5.0? 5.1?), my first full scan took about 45 minutes because of the repopulating process, but only took about 25 minutes this time (normal full scan after that’s been done is typically 8-9 minutes).

Anyone else noticed this improvement?
