Chapter 3 Concurrent Handling Capacity of the Server 3.1 Capacity Capacity Capacity Capacity: The number of requests handled by the Web server per unit of time Maximum Capacity Capacity: The maximum number of requests that the server can handle per unit of time Stress test: Simulate a large number of concurrent users continuously sending HTTP requests, calculate the total duration of the test, and calculate the throughput rate accordingly.
