Multithreading and leveraging multiple cores

You may be wondering how performance may vary when invoking additional processor cores—as mentioned earlier, this can sometimes have an unexpected effect.

In this case, we should expect only improved performance in our dynamic requests and static requests. Any time the cost of context switching in the OS might outweigh the performance advantages of additional cores, we can see paradoxical performance degradation. In this case, we do not see this effect and instead see a relatively similar line, as shown in the following graph:
