A load test is done by simulating the real time user load on the application under test, and this determines how the application responds when multiple users hit the server simultaneously and it reveals the application’s response time, CPU and memory usage, network and bandwidth usage.

Joe Obbish correctly noted that this test could be lacking in its reflection of some real-life scenarios in the sense that a big chunk of the run time is due to async network I/O waits (ASYNC_NETWORK_IO wait type). This time the wait info has no async network I/O waits, and you can see the significant drop in run time.

From experience, record & playback is brittle, same as for functional test automation. One could do the recording to analyze the queries to replicate in load yes, but in practice there are better and alternate ways to do that like with a network proxy, Wireshark, or the network analyzer tab/tool in browser’s debug toolset.
