In the upcoming minor release of core, there will be a cache introduced for the bucketlist. This cache will affect the memory footprint of stellar-core. The default configuration will actually increase memory usage of captive core from ~2.5 GB to ~5-6 GB. However, these caches will be mostly of benefit to validators and not watcher nodes. In the captive core library we want to ensure the default configuration of the caches does not result in an increased memory footprint.
