This reduction in contention dramatically reduces the synchronization costs compared to a traditional thread-pool-based approach.
跟传统的基于线程池的方法相比，减少争用会大大降低同步成本。

Out of the box you one based on.net's thread pool system and one that USES the synchronization context framework.
开箱即用的实现就是。NET的线程池系统以及使用了异步上下文的框架。

The application service provider implements the pool manager in its memory space and can optimize resource usage by dynamically altering the pool size, based on demand.
