 All gateways and tunnels are active from the Azure side, so the traffic is spread among all 4 tunnels simultaneously, although each TCP or UDP flow will again follow the same tunnel or path from the Azure side. Even though by spreading the traffic, you may see slightly better throughput over the IPsec tunnels, the primary goal of this configuration is for high availability. And due to the statistical nature of the spreading, it's difficult to provide the measurement on how different application traffic conditions will affect the aggregate throughput.
