> There are two obvious optimizations possible in the code that handles installation of a new topology.
> 1. Currently a new topology is not confirmed until the node successfully sends START_STATE_TRANSFER requests to all nodes it wants to fetch segments from. This does not wait for the actual data to arrive but it still blocks quite a lot. To fix this we need to confirm the topology right after transactions were received.
> 2. Fetching transactions from other members is done serially. To improve it we could split it into multiple concurrent tasks.
