why didn't link aggregation reach a 2g transmit speed when combining two 1g ports?

Setting up link aggregation on the switch such as combining ports 3 and 4, does increase overall bandwidth between devices. besides, the LAG (Link Aggregation Group) algorithm plays a key role in how this bandwidth is utilized. This algorithm distributes data flows across the aggregated links based on criteria like source and destination MAC addresses. While this allows for more efficient utilization of combined bandwidth, each data flow is still limited to the maximum speed of one port, which in this case is 1Gbps. Therefore, for any single data flow, you will only achieve a maximum of 1000Mbps, aligning with the capacity of one port. This behavior is typical in link aggregation to optimize overall network efficiency rather than boosting speed for individual data streams.
