Some users here have recently reported significant slowdowns with some testing suites. They claim the addition of a few directories to a certain path triggered the performance degradation and are asking me about change notification handles for the CIFS service.
Searching the NOW site, CD docs, and the toaster mailing list archives just gave me hits on "Yup, it's there," but nothing else.
Can anyone reference a pointer on more information? What the ONTAP limit is? If there are any tunable parameters?

Hi, There are no "hard" limits to change notification handles and no tunable parameters either.
Where were the new directories added? If the path to a leaf item became longer by adding additional levels of directories, and each directory in the path was change-notify active and watching subtrees, then every change at a lower level is posted to all upper levels that are watching subtrees. This will add some overhead to the processing.
