What is the role of the 'MaxWorkerThreads' and 'MaxIoThreads' settings?

The settings 'MaxWorkerThreads' and 'MaxIoThreads' play a crucial role in the management of threads in the server, directly impacting its performance and ability to handle requests effectively.

The 'MaxWorkerThreads' setting controls the maximum number of worker threads that can be utilized to process incoming requests concurrently. This is essential in ensuring that the server can handle multiple requests simultaneously without delays. When the number of incoming requests exceeds the limit set by 'MaxWorkerThreads', additional requests must wait until a thread becomes available, which can lead to slower response times.

Similarly, 'MaxIoThreads' governs the number of threads allocated for performing I/O operations, such as reading and writing files or accessing databases. This setting optimizes the server's capability to manage input and output operations alongside request processing. An optimal configuration of both settings allows for better resource management, enabling the server to efficiently handle high volumes of traffic and maintain overall system performance.

In contrast, the other options address aspects unrelated to thread management. The second option regarding user session limits pertains to session state management rather than thread control. The third option about managing maximum file upload sizes is related to request validation and not to threading. Finally, the option concerning scheduling database backup tasks deals with data protection and
