如果没有足够的线程提供服务，则传入请求(特别是Web请求)可以在AIO工具中排队，而不是立即被拒绝。
Incoming requests (especially Web requests) can be queued in the AIO facility, rather than be rejected immediately if there are not enough threads available to service them.
你还能让线程列表根据所标记的“flag”进行排序，来确保被标记的线程排在前面，你也可以使用调试工具条的下拉列表对线程加以过滤。
You can sort the thread list by "flagged" to make sure your threads are the ones at the top, and you can also filter the threads drop down in the debug location toolbar.
要做到这一点，您需要了解一些相关的工具，这些工具允许您使用线程来提高CPU的性能，而这正是本系列文章中最后一部分内容的研究范围。
