Group policy conflicts or lack of tight filters are what I have usually fou=
nd as the root cause of this..
I would also echo I/O (or RAM) as being a much more likely resource culprit=
than CPU. In the VM age, storage (for speed not capacity) is king.

Just my two cents :-)

While we know that system performance can vary drastically, depending on O=
S, memory and processor speed (our oldest systems are currently Optiplex 21=
0L=92s-P4 3Ghz with 1-2 GB of RAM), Le Moyne College is looking to determin=
e what your institution might consider a =93typical=94 boot up time for you=
r standard campus configuration computers=85If you could answer the followi=
ng it would be greatly appreciated!!
1) Size of your campus
2) Campus computing replacement cycle duration
3) =93Standard=94 campus computer configuration
4) Approximate average boot time in minutes (from power on to usable d=
esktop)
We would like to find out where out computers stand compared to other insti=
tutions and be able to tell our employees how ours stack up to other insti=
tutions norms=85.
Thanks in advance=85.
