of the I/O queue and the emit mode of the I/O request. If the SVCTM is closer to await, stating that I/O has almost no waiting time, if the await is much larger than SVCTM, the I/O queue is too long, the response time of the application gets slower, and if the response time exceeds the allowable range of the user, consider replacing the faster disk and adjusting the kernel Elev Ator algorithm, optimize the application, or upgrade the CPU.The queue Length (AVGQU-SZ) can also be used as an indica
