Rubbish Speeds

One final point - your upload speed can affect the download -I find I get the best results if I set it to one sixteenth of my total eg for 256 it should be set at 16ks.

Actually, the quoted upload speed you were probably given for your ADSL connection was in kilobits/sec -- while BitTorrent's upload speed limit is in KiloBYTES/sec.

So 256 kilobits/sec is really a theoretical max speed of 32 KiloBYTES/sec and your recommendation of 16 KiloBYTES/sec is really half of that.

BUT... BitTorrent is dealing with how fast the FILE is sent out, not how much bandwidth is used doing it. So sending the file out at 16 KiloBYTES/sec may well take 140 kilobits/sec (instead of 128) to do it!

This is why even if you have 256 kilobits/sec total upload speed and NOTHING else going on (just seeding a finished torrent) that you cannot upload at 32 KiloBYTES/sec -- to do that would take probably 270-300 kilobits/sec bandwidth.

I use AnalogX Netstat Live to monitor realtime my bandwidth useage -- I'm not pulling the numbers out of the air, these are the real numbers I'm seeing. It's also helpful at spotting when unknown programs (read: viruses and spyware) are eating my precious bandwidth!

This allows me to push my upload speeds to near their maximum, because I know when I'm hitting my upload bandwidth limits.

Hi.

I've been trying for a week to speed up my bittornado. I have searched through google and every forum I can find but to no avail.

When downloading I have a green light plenty of peers/seeds but am chuffed to bits if d/l speed stays at 3kbs (normal is 0-1, mostly 0). Upload averages at about 10kbs.

I have forwarded all ports and allowed program to act as a server through zone alarm but still nothing.

The only things I can think of is a may have put the wrong IP address in the box when forwarding ports (Ihave tried my ip and the gateway ip, sorry dont know the diffrence)

Or it could be something to do with my ISP which is NTL Broadband. I have e-mailed them 3 times asking if its something to do with them but have received no reply.

Any advice would be very, very, very much appriciated.

summary:

you seached everything
you forwarded all ports
you gave it server status in ZA


1-why do you have ZA if you have a router?
2-first thing said in nearly every BT page is: UNINSTALL ZONE ALARM, it doesnt work with BT, even in server status
3-ur ISP wont want you downloading shitloads of data, so theyre prolly not gonna tell you what you're doing wrong (why should they, they usually only throttle p2p ports, so theyre definitly not gonna help you)

btw, if #3 is you problem, use a diffrent port.....

It would seem No 3 is my problem but what other ports other than 6881-6889 would I use?? these are the only ones I have found listed?

Thanks

Try using a range of about 10 ports between 49152-65535.

[bilko]

ah i didnt think of that, increase the number of ports forwarded?
i kinda go on the basis of one prot per torrent so i have 6 ports open and i never leave more than that going...if i opened more it may help speed?

sounds good but cant be true - Azerus only requires 1 port

[rf9rider]

Opening too many ports will result in more problems.
Just try a port between 49152-65535.
As Storm said, it might be your isp throttling 6881-6889

[barryk32]

Thanks. I have gone through port 49152 and d/l speed is always between 3-13 which although is not fantastic it is acceptable (its like being stuck in traffic its not that bad if you are always moving, its when you are stood still you start to get annoyed).

I can come back after an hour and find the percentage completed has increaced which I could not do before.
