I upgraded my server yesterday to 10.3 in my testing environment. I have distributed the client to two Windows XP workstations and my login times are now well over 2 minutes until the desktop is displayed. With the server and client at 10.2.2, my login times were down to under 30 seconds.

I have also noted that my server seems very sluggish also. SLES 11 on very beefy server... Ran top and all looked fine, but took server forever to reboot. Previously it would only take a minute or two.... Did not come back for close to 5 minutes....
