What is a valid threshold to say when the system I/O Wait is too high? Our system currently averages 25% IO Wait while CPU Busy is 60+% . At
times IO Wait will peak at 60+% and CPU Busy will drop to 30+% and others IO Wait will drop to < 5% and CPU goes to 90+%. Is there a valid
determination as to when the system is considered IO bound vs CPU bound?
Thanks in advance for all advice.
