On an N-processor system for a work queue that will hold entirely compute-bound tasks, you will generally achieve maximum CPU utilization with a thread pool of N or N+ 1 threads. 若在一个具有N个处理器的系统上只有一个工作队列,其中全部是计算性质的任务,在线程池具有N或N+1个线程时一般会获得最大的CPU利用率。
Any page that is I/ O-bound rather than compute-bound and that takes more than a few seconds to execute is a candidate to be an asynchronous page. I/O绑定而不是计算机绑定且需要很长时间执行的任何页面很有可能成为异步页面。
