Hullo Everyone,

Here is the data from my Statistics panel;-

Overall Tasks: Total:11 / Running: 9

TCP Connections: Established: 110 [MAX:Unlimited] / Half-Open: 9 [MAX:10]

LAN IP: 192.168.1.2

WAN IP: 82.XX.XX.XXX

Listen Port of TCP: 12784

Listen Port of UDP: 12784

Windows Firewall: Added [TCP opened, UDP opened]

NAT port mapping: Added

Overall Download Rate: 20 kB/s Max Connection Limits: 50 per task

Overall Upload Rate: 67 kB/s, including LT seeding: 55 kB/s Upload slots: 13

Free Phys Mem: 1.04 GB (Min to keep: 50 MB)

Disk Cache Size: 50 MB (Min: 6 MB, Max: 50 MB)

Disk Read Statistics: Request: 28439 (freq: 0.5/s), Actual Disk Read: 20784 (freq: 0.3/s), Hit Ratio: 26.9%

Disk Write Statistics: Request: 86264 (freq: 0.7/s), Actual Disk Write: 21816 (freq: 0.0/s), Hit Ratio: 74.7%

Total Downloaded: 102.88 GB

Total Uploaded: 39.90 GB

I am running BitComet v 1.09 on Windows XP with SP3 on a computer with a 2.0 GHz CPU and 2GB of RAM.

I have checked my Internet speed on http://www.speedtest.bbmax.co.uk/ and it seems to be running at 9801 kbps.

The port forwarding seems to be OK as the green light is on next to the WAN bottom right.

Using Norton Internet security, but configured to allow BitComet “always”

The ports are all open yet the collective download speed of 9 downloads is only 20kb. Normally my BitComet races along and achieves speeds of anything between 150kb and rarely 290kb!

Question; Can an ISP throttle BiComet but leave the bandwidth apparently intact? (I have ticked the “always” selection in the encryption

option.) Also, I normally download overnight to avoid upsetting Virgin Media. Even IE seems to be slow on the ineternet despite

the apparently excellent speed.

Question; Does anything in the statistics panel strike the experts out there as obviously wrong? Have I got the settings wrong in any way?

Any advice very gratefully received.

Thank you, Peter

You’ve left out the most important piece of info for your case: What is your tested upload speed?

Set the Global Max Upload Rate to 80% of that speed (expressed in kB not in kb - where 80kb/s = 80/8 = approx. 10kB/s). Also let your number of concurrent running tasks (downloading+seeding) be only so high that every one of them gets at least a 8kB/s share of your set upload rate (preferably 10kB/s or more - the higher the better).

The more you’ll give the more you’ll get for any task (that is, if it is a healthy task, a.k.a. well seeded).

Overall Tasks: Total:11 / Running: 9

That will probably create your problem right there. 'way too many tasks running.

Your connection almost certainly will not support so many. Reduce it to one download task and one seeding task, then look at the upload bandwidth for each. This needs to be at least 1/3 of your tested (as Wiz says) upload speed, and never less than 8 KB/s. Faster is better, makes you a more desirable trade partner.

If you’ve got a really fast upstream connection, then MAYBE you can add another download task. But if the upload speed of any of them drops much, or drops below 1/3, you’ll know you cannot. Most can’t.

If you run 9 tasks at a time, your bandwidth is divided among all of them. All of them are starved. Other peers do not see your total bandwidth, they see only what that one task (that they’re connected to you about), is getting. From their viewpoint, you look like a very slow, unreliable trade partner. They will try to find someone better, and they’ll usually succeed. You’re left exchanging with only the slowest and least reliable peers yourself – everybody faster has found someone faster for their transfer slots.
