Creation Rate
This panel shows the incremental object creation rate for the application as observed at each
garbage collection event. The increment at each data point is the amount of elapsed time since
the previous GC event.
The rate of object creation can be a good measure of your application's overall performance. By
correlating GC events with changes in the object creation rate, you can discover opportunities for
improving this performance through heap parameter tuning.
