I would like to check if there is an undocumented limit to how many
directories in a particular folder will break/slow-down/or hung Console One
and NWAdmin.

Our user home directories have just reached 33,000. We noticed that if we
try to browse these folders using Console One or NWAdmin, my workstation
will go 100% CPU utilization and it will take forever for Console One to
display these folders. Most of the time after 10 minutes of waiting, we are
forced to close Console One.

Using Windows Explorer, it will take approx. 10 to 15 seconds.

We are using IManager in the meantime as a workaround.
