I can also see the consumption to be levelled out at 8 Mbps for minutes or hours so it looks like there would be a need for more bandwidth. Yes the Tor network does need more bandwidth, particularly for exits. > My question: why can't I see the bandwidth usage going above 8 Mbps and making use of the allowed burst? Btw, I'm typically using the latest stable tor, currently the relay is on 0.4.0.5. The burst is over a very short period of time. I think it's about 1 second. The rate is averaged is over a slightly longer period of time, and includes any burst bandwidth. That is, if the bandwidth burst to 12 Mbps in the last second, the bandwidth in this second will be 4 Mbps. The lower bandwidth in the next second keeps the average to 8 Mbps.
