How should the value 1.0 for Load Average over 1 minute be interpreted on a server with one processor?

The Load Average 1.0 value over 1 minute on a server with a single processor means that, on average, the server was fully loaded during the last minute. That is, on average, one task was either executing or waiting for CPU time without delays. If the Load Average value is above 1.0, it indicates that the load exceeds the capacity of a single processor, and tasks start to queue. If it is below 1.0, the processor is not fully loaded.
