逻辑CPU个数=物理CPU个数_cores个数_2(开启超程)
查看物理CPU、多核和逻辑CPU
cat /proc/cpuinfo
load到底多大比较合适？
逻辑CPU个数*0.7

进程状态
R running or runnable (on run queue)
D uninterruptible sleep (usually IO)
S interruptible sleep (waiting for an event to complete)
Z defunct/zombie, terminated but not reaped by its parent
T stopped, either by a job control signal or because it is being traced
亲，load怎么了？已经飙到了20+
load是如何计算的
load = run queue length (运行队列中的等待进程和正在执行的进程数)
