| D | proc.txt | 1373 - iowait: In a word, iowait stands for waiting for I/O to complete. But there
1375 1. Cpu will not wait for I/O to complete, iowait is the time that a task is
1379 on any CPU, so the iowait of each CPU is difficult to calculate.
1380 3. The value of iowait field in /proc/stat will decrease in certain
1382 So, the iowait is not reliable by reading from /proc/stat.
