Summary
On readonly nodes that have p2p disabled or doesn't expose public IP fastSync mode can be used to improve the download block frequency. Node that have fastSync enabled will use the 8 sec rate over the default 60 sec rate to improve sync. This results in more frequent block download actions.
Feature can be enabled via: CORE_BLOCKCHAIN_FAST_SYNC env variable.
