) Gossip packet processing is composed of two stages: * The first is consuming packets from the socket, deserializing, sanitizing and verifying them: https://github.com/solana-labs/solana/blob/7f0349b29/gossip/src/cluster_info.rs#L2510-L2521 * The second is actually processing the requests/messages: https://github.com/solana-labs/solana/blob/7f0349b29/gossip/src/cluster_info.rs#L2585-L2605 The former does not acquire any locks and so can be parallelized with the later, allowing better pipelineing properties and smaller latency in responding to gossip requests or propagating messages.
