Do you have any performance measurements to share? Note that the sensitivity can be set as shown in the [SensitivityModifier](https://github.com/openjdk/jdk/blob/41de506ed6c9dc0331c2b6ae99c11623df05f34a/test/jdk/java/nio/file/WatchService/SensitivityModifier.java) test. ------------- PR: https://git.openjdk.java.net/jdk/pull/8479
