> In deployments using large number of tags, significant amount of memory usage
> can be reduced by:
> * cache has as many instances of a tag as the number of resource
> associations. Enabling dedup of tags eliminates duplicate tag instances
> * not initializing few collection members with new collection instances
> (Map, List) - as much as 25% of memory needed to cache tags
> * skipping serialization of empty collections can reduce the size of the
> JSON downloaded to plugin
