... There's no difference in "background" traffic. You don't notice why you have spikes like in rafi's graph? Turn off DHT, RSS, or bt.scrape_stopped. @ rafi: Your graph actually doesn't give much information without context.. it shows at roughly 5 minute intervals your uT was doing SOMETHING. The hour-graph (30 sec. intervals between update) shows what I notice, that probably those spikes are DHT traffic(It takes about 2 minutes to update your cache both IN and OUT). I guess you don't use RSS, or you'd see more overhead every 15 minutes (or down to 5)... My 15 feeds of 20 items each pumps out 100 KiBps down, 5 KiBps up sustained for about 30 seconds every update interval.
