I am trying to trace the boot time of a Windows 7 Professional machine and found the following times:
Phase #, Phase Name, Start Time (s), End Time (s), Duration (s)
1, Pre Session Init, 0.000000000, 6.218684586, 6.218684586
2, Session Init, 6.218684586, 19.716180585, 13.497495999
3, Winlogon Init, 19.716180585, 164.393575644, 144.677395059
4, Explorer Init, 34.856013361, 39.280802294, 4.424788933
5, Post Boot, 39.280802294, 85.280802294, 46.000000000
The winlogon init seems to take a long time. What can be a reason?
Have a look at Mark Russinovich's blog, specifically The Case of the Slow Logons . The guy is a demi-God, and this particular article is very good.
BTW, what tool are you using to capture/present your data - looks very good?
