There is a Windows performance counter for the number of page faults a process generates. Is there a rule-of-thumb threshold at which performance will be affected?

性能总是受到页面错误的影响 - 内存访问速度要慢得多。
一旦您的整个机器开始达到每秒约 100 个页面错误,您的交换文件的随机访问性能就非常接近饱和了
Performance is always affected with page faults - the memory access is much, much slower.
Once your entire machine starts hitting around 100 page faults/s, you're very close to saturating the random access performance of your swap file
