What is CPU Overload?
CPU congestion is a type of bottleneck caused by an excessive demand on the capabilities of a processor on a given network or system.
The central processing unit (CPU) is a key element of any hardware system. It controls the processing of data in the entire system. As networks and systems become more complex, more demands are placed on the CPU or CPUs.
A common example of CPU congestion is in a virtual network. A virtualized hardware network involves the creation of many different virtual or logical components, including workstations known as virtual machines (VMs). Virtual machines are partitioned by existing hardware setups and given resources to carry out their tasks. One of these resources is the virtual CPU. If VMs are not grouped properly, layered on top of each other, or if there is insufficient CPU capacity, CPU overload can occur.
The term 'CPU congestion' can be used in the larger context to determine why network congestion exists. For example, IT pros can say that network congestion caused by too many packets accessing the same space might be due to insufficient CPU allocation. Alternatively, they could say that there is just too much traffic on a certain part of the network. The use of the term CPU congestion suggests that the network congestion in question is directly related to the provision of processor resources.
