> The bundle archive implementation tries to limit disk accesses by only reading variables from the disk the first time and the caching the result. In some cases, though, it is not too smart. Like in BundleArchive.getRefreshCount() where it checks if a file exists and if not then simply returns the default value. This means all default values will incur a disk access to check for file existence. It should cache the default value after first read too, to avoid future disk accesses.
