i input 'sysstat -x 'to check system, CPU util is up to 90% for long time. volume access has so slowly. ‘qos statistics latency show' display 190ms. 'systat -M’ display 16 core cpu all up to 90%. The disk untility is lower than 70%. please advice how to solve/reduce CPU uitil to 50% ?
Ok first, start with the commands in that KB article, and read through it to figure out what is causing it. If it is a volume listed, then you will need to reduce, modify, or move that workload, or throttle with QoS.
