This is all explained in the book, in later paragraphs. Keep reading. In short, it uses sleep time. Process sleeps more than it wants to run implies that it is waiting on I/O more than not. The larger the sleep-to-run ratio, the more I/O bound it is. The smaller the the ratio, the more processor bound it is. Robert Love -- Kernelnewbies: Help each other learn about the Linux kernel.
