My apologies if this is somewhere in the FAQs, but I couldn't find it. I am an occasional user of BitComet, and never had this problem before.
Using BitComet 64-bit v1.31 on a fast Windows 7 machine, Ethernet cable, Netgear DG834Gv4 modem router with DGTeam Firmware, Ports properly forwarded, ADSL2+ with DL connection 16.5Mbps, UL 1020Kbps, (actual tested DL throughput approx 14.5Mbps, UL approx 800Kbps, Windows Firewall, Norton 2012 Antivirus:
I found that according to my Router Stats, I downloaded 82MB of files from a 2.45GB torrent (all the unwanted files unticked). Started with last good BC settings which used to work fine - DL 60Kbps, UL 10Kbps - but found that download was very slow so increased DL to 200Kbps. So increased again DL to 500Kbps (!) and UL to 30Kbps (on the basis DL:UL ca 15:1). Still very slow. Seems to be because was downloading lots of bytes.
Checked my monitoring software: it had recorded over 3 GB downloaded for 85MB of files!!!! 35x! (In this case it was at the Router, all LAN traffic excluded). Nothing else was running at the time. My monitoring software correlates well with bandwidth used for other stuff (e.g. TV on demand etc)
Files virus checked after downloads, nothing found.
So did some more downloads on my old PC, XP 32-bit with BitComet v0.99. Connection, settings, modem, forwarding, A-V etc etc as above. This time monitored bandwidth at the local machine. For 11MB of files, the monitor (different software to the other moniitor) showed that about 86MB had been downloaded. So, this time 8x!
The only thing that's changed recently is that I changed from ADSLMax (up to 8Mbps connection) where 60Kbps Down/10Kbps Up worked fine; to an unbundled connection at 16.5Mbps. There was (allegedly) no P2P restriction at the time I was on BitComet.
Can anyone explain this, and how to remedy it? (My montlhy FUP cap is 100GB, but if these download stats are really correct, this is not sustainable....)
