I've been testing login times for our current environment:

Netware 6.5 SP5
ZENworks 7 SP1
Novell Client 4.91 SP2

I have found that the additional delay of applying a group policy to users
on login is 20 seconds.

I thought ok lets change the way the group policy is applied to a
scheduled event (every 3 hours) rather than user login. The net result is
an actual increase of login times by a further 20 seconds!

What am I doing wrong?
