he's on a very long plane flight, but i'll try and channel richard:
"it depends."
how did i do? :-)
You have learned well.
Sirdhar: Unfortunately theres no way we can answer your question ( or
even make a SWAG) without known how much idleness is in your normal
workload. Automatic Power Management only makes a big difference if
there is a lot of time spent idle. If you are running Tam-Tam the
entire time then turning off aggressive suspend/resume will make zero
difference.
powerd tracks this though so if you can collect some powerd logs from
some of your users then we can make a guess at figuring out what your
impact will be.
powerd logs are located in the ~olcp/power-logs directory. Copy all the
files in there off of several machines that have been used in the
classroom and send them to me and we can take a look at what sort of
profile you have.
What build are you basing your images off of?
