My understanding is that the persistence (which finally actually worked in 7.1.00.002) is the feature whereby the pre-fetched cache (and possibly plus anything fetched after that - I'm not sure of that) is retained in a file so that if you restart tomcat (or it crashes and restarts), the persistent cache file is re-read in less than one minute as opposed to the 24 minutes that it normally takes to build it from scratch on my system.
