It'll be speeded up further after we enhance hivemind to support microfork recovery. In the past, hivemind has always stayed 2 blocks behind the current block (i.e. 6 seconds in the past) because it didn't have a way to recover if it put data in the database that gets changed due to a microfork. We do have a plant to enhance the data that is placed into the database, so that hivemind can revert data from a microfork. Once that is possible, we can allow hivemind to directly report data from the head block of the blockchain, and this delay will no longer be necessary in condenser.

By the way, this is deployed in production now, just tested it and it works.
