Per MaxDegreeOfParallelism's documentation [LINK] : " Generally, you do not need to modify this setting . However, you may choose to set it explicitly in advanced usage scenarios such as these: When you know that a particular algorithm you're using won't scale beyond a certain number of cores. You can set the property to avoid wasting cycles on additional cores. When you're running multiple algorithms concurrently and want to manually define how much of the system each algorithm can utilize. You can set a MaxDegreeOfParallelism value for each. When the thread pool's heuristics is unable to determine the right number of threads to use and could end up injecting too many threads. For example,
