Description

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
