    【Linux】《how linux work》第八章 流程和资源利用的近距离观察(第一部分)

    This chapter takes you deeper into the relationships between processes, the kernel, and system resources. There are three basic kinds of hardware resources: CPU, memory, and I/O. Processes vie for these resources, and the kernel’s job is to allocate resources fairly. The kernel itself is also a resource—a software resource that processes use to perform tasks such as creating new processes and communicating with other processes. Many of the tools that you see in this chapter are often thought of as performance-monitoring tools. They’re particularly helpful if your system is slowing to a crawl and you’re trying to figure out why. However, you shouldn’t get too distracted by performance; trying to optimize a system that’s already working correctly is often a waste of time. Instead, concentrate on understanding what the tools actually measure, and you’ll gain great insight into how the kernel works.
