Network load indicates the level of activity both on a particular interface and as a global value. All current LoadMaster models contain 10/100/1000 interfaces which can pass a maximum amount of 1Gbps. The other constraint on network load is the global throughput value. This value represents the maximum amount of network traffic which can be processed at a given time. Increases in network load have a consequence of driving up CPU utilization as each packet requires processing in order to determine what needs to be done with it.
