Well, it isn't possible to make OS states identical, since they are
different. Situation was as "identical" as possible. No additional
background jobs\applets were running. I had opened browser and
established connection in both cases. But connection/browser were
inactive/doing nothing... It's difficult to make sure what were doing
something and what were not...

I guess the reason of speedup is memory
managment. I suppose it run slower on my friends' computer because he
uses KDE, and that desktop uses more background jobs|memory...

Thanks for the answer.
