What is the meaning of running input/output operations that surpass the number of CPUs?

edit

Running input/output operations that surpass the number of CPUs means that the system is not able to keep up with the incoming or outgoing data, causing a bottleneck. This can lead to slower performance, longer wait times for user requests, or even system crashes. It is essential to ensure that the input/output operations are optimized for the system's resources to avoid these issues.
