Here US + SY reference value is 80%, if us+sy greater than 80% indicates that there may be insufficient CPU.The WA column shows the percentage of CPU time consumed by IO waits. Here WA has a reference value of 30%, if WA is more than 30%, it indicates that the IO wait is serious, this may be caused by a lot of random access to disk, or the bandwidth bottleneck of disk or
