> Some applications load a lot of classes using custom loaders. This PR improves the start-up performance of these apps when using a "static" CDS archive:
> Here are performance numbers for the Eclipse IDE:
> Static Archive Before: 7.31 sec (classlist does not include custom loader classes)
> Static Archive After:  6.49 sec (classlist includes custom loader classes)
> Dynamic Archive:       6.62 sec
