We know that very large brains, such as Matrioshka brains, are constrained by light-speed communication lags. Even when the structure includes a wormhole bus there are communication lags in the space around the wormhole link, and the links have a limited bandwidth in any case. So the consciousness and subjective experience of time of a Matrioshka brain must be fractured into innumerable time-separated domains. On the other hand the subjective speed of thought of each individual location would be much faster than human mentation. This is not comparable to anything we are familiar with, apart from maybe a large distributed human empire communicating by sailing ship and horse-rider.
