We have test running with McAfee 8.8 that show a 30% improvement. I will run another pass with it completely removed. The Profile issue is the one that is vexing. The test machine only has one user and it is not a romaing profile. (Will double check, but that is not our default configuration) Furthermore, on 3 test runs on the Test PC, the folowing pattern emerges: WinLogonInit Breakdown Test Pass CreateSession Logon Logon.Profiles Logon.GPClient StartShell 1 104 164309 161111 3191 3 2 75 187395 72991 114395 2 3 176 110287 110246 0 2 I wish there was a batter way to format that for you but the delay moves from PRofiles to GP Client. Test pass 1 is in default config (you have that trace) Test pass 2 is with MICMUTE and SFTLIST Disabled Test Pass 3 is with all Lenovo services disabled (admittedly a shot in the dark) Why would the delay flip flop? No policy changes are happening.
