I don't think it's that because I get the same behaviour if I've been 
actively using the machines or if they've been left for a while. Doesn't 
feel like a hard drive waking up. Feels much too slow for that too.

Is there a way of logging what takes what amount of time to execute 
during boot up, logging in and logging out?
