      Description

        The package matching algorithm in the checkPackageAccess method can be optimized in several ways to improve performance:

        1. Restricted packages that are longer than the package being checked can be skipped; there is no need to compare them since they will never match
        2. A more efficient algorithm can be used when checking if the packages are equal to each other
