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. -- Best regards, Victor "ErV" Eremin.(mailto:[EMAIL PROTECTED])
