另一方面，不用牺牲性能和可伸缩性，Node的请求就可以延长一段时间，因为Node是个完全异步、单线程、单进程的框架。

On the other hand, in Node requests can extend for long periods of time without sacrificing performance or scalability, as it's a fully asynchronous, single-threaded, single-process framework.

用处理器与收集间隔的比值表示的CPU使用率的分布情况，该信息有助于识别单线程的进程。

Distribution of CPU utilization by processor over the collection interval — useful in identifying single-threaded processes.

由于闪存的时延是亚毫秒级，所对对于单线程的进程而言可以有很大的IOPS。

And since the latency of flash is sub-millisecond, it should be possible to see that, even for a single-threaded process, a much larger number of IOPS is possible.
