Loaded Classes

HPjmeter displays the number of classes loaded into memory for processing. This number usually

stabilizes over time as processing progresses.

Guidelines

• The number of classes loaded at any one time tends to oscillate within a narrow range; typically

less than 2 percent of all loaded classes will be unloaded or reloaded during application

processing.

• If the number of loaded classes constantly grows, it indicates a possibility that the new classes,

possibly dynamically created, may eventually fill the available memory and cause the

application to crash.
