All the overhead of switching contexts is applied to the thread one time.

切换上下文的所有开销都一次性应用到线程。

Due to the overhead involved in context switching to a thread or process for any amount of work, systems with small-scope granularity are often inefficient and suffer from low performance.

由于任意工作量的一个线程或进程的上下文切换涉及到的开销较大，小粒度级的系统往往效率低下且遭遇低性能问题。

This avoids network latency and the overhead of inter-process communication, as well as context switching in the operating system, further contributing to extreme speed.

这样就能够避免网络延迟、进程间通信的开销以及操作系统中的上下文切换，从而进一步提高速度。

Nasi Lemak Antarabangsa has a legion of devoted followers, many of whom turn up early (the place opens at 7.45 p.m. and closes at 11 a.m.) and sit patiently at plastic-covered tables, waiting for the management to shed light on matters by switching on the fluorescent tubes overhead.
