tb _ to_xs:用来将tb滴答数转换成xseconds。
您可通过比较三种数据点中每传输1KB数据的取样滴答数清晰地看到这一点。
You can see this easily by comparing the sampled ticks per KB transferred number between the three data points.
在Linux内核中,时间由一个名为jiffies的全局变量衡量,该变量标识系统启动以来经过的滴答数。
In the Linux kernel, time is measured by a global variable named jiffies, which identifies the number of ticks that have occurred since the system was booted.
在最低的级别上,计算滴答数的方式取决于正在运行的特定硬件平台;但是,滴答计数通常在一次中断期间仍然继续进行。
The manner in which ticks are counted depends, at its lowest level, on the particular hardware platform on which you're running; however, it is typically incremented through an interrupt.
