public class CPUSpeedBean

extends javax.swing.JPanel

implements net.jini.lookup.entry.EntryBean, java.io.Serializable

An entry bean class corresponding to CPU Speed entries.
Inspired by CapacityBean of "Core Jini," by W Keith Edwards.

CPU speed is measured in abstract units based on the number of computations per second the machine can complete under a given load. It is measured with a one-second long test every thirty seconds.
