Upload Bandwidth

[foussais]

Good morning everyone,

I am new to uTorrent, so I would like to thank everyone involved with its development - what a fantastic concept!

I have read many of the FAQs and I think I have set up my connection properly - it certainly seems to work well, at speeds which are reasonable. I have done as requested, and left the application on-line to allow seeding etc, but seem to have a problem with uploading which is blocking my Internet access.

I have an ADSL connection rated at 1.2Mb/s down/160kb/s up - I have set my global upload limit to 12kB/s, and the upload summary at the bottom RH corner of uTorrent shows an upload rate of around 8-10kB/s.

However, the ADSL Modem Status Monitor shows the transmit rate maxing at 160kb/s almost all the time, unless I stop all uploading. This is preventing me accessing the Internet while uploading - I thought there should be sufficient bandwidth available for at least slow access.

I have checked for virii, adware and spyware and there is nothing to explain the loss of transmission bandwidth - I am a novice at this type of operation, and have probably missed something obvious, but I would be grateful for any advice.

Best wishes to all

have you used the speed guide settings aor changed the number of active torrents by hand?

Normaly when using the recomendet settings acording to your UL speed thsi problem should not happen.

If you have not more than the recomended torrents / connections active and it is still not possible to surf okay, maybe your network equippment is some kind of the crappier ones for sale?!

How fast are you downloading?

[foussais]

Hello Firon - thanks for your answer

I'm downloading between 8 and 28kB/s, and uploading 2 torrents at around 8kB/s, although I must say it is better this afternoon.

My DSL Modem Status is showing Transmission between 100 and 150 kB/s and not maxing at 160kB/s all the time, and I have now got Internet access at a reduced speed.

Hope this helps - best wishes

Okay, this is why I hate kB and kb.

Use KiB for kilobytes, and kb for kilobits. That way it's not ambiguous.

[µtorrent-Guest]

Firon, just to be "correct" (german translated "D:klugscheißerisch")

KiB is not Kilobytes. 100% correct it is spoken KIBIBYTES ;-)

I know, but it's easier to explain that way.

[foussais]

Hello Firon - sorry for the ambiguity, and the delay in replying (the day job!)

I'm downloading at between 10 and 30kbyte/s, and seeding 2 torrents at around 10kbytes/s.

My Internet Connection is ADSL, theoretically 1.2Mbit/s receive and 160kbit/s transmission

This afternoon, my Modem Status monitor is once more showing the Transmission rate maxing at 160kbit/s and my Internet Connection has once again slowed down and become unreliable, although upload and download rates are similar to yesterday when the Modem Transmission Rate dropped and Internet access became easier.

Hope this helps - best wishes

foussais, if your upload is (only) 160 kbit then having 2 torerents seeding and at least one third downloading produces much more bandwith overhead than good for that UL speed.

See the values that CTRL+G recommends for max active torrents global connections ect. with UL speeds 128 or 192. In both cases NO more than 1 active torrent at a time.

So, obey the settings sugested and if you have THAN problems to use your internetconnection come again. Right now you are stressing your UL line to much with the protokoll overhaed for the handling of this many torrents/connections.

your 1mbit DL line can download torrents with fullspeed (when the swarm CAN give you that speed) if you obay the settings rules for your Uploadspeed and you can smoothly surf the net.

Try it for example with this Creative commons torrent . connection to german ISP backbone Datacenter as one of the peers possible!

(You can even see which leechers do not obay the settings rules. They going very slowly up in their percentage)

[Firon]

10 KiB/s up with TCP overhead is like 96-112kbit/s, plus the overhead from downloading, and other BT/TCP/DHT overhead, you'll easily reach 160kbit.

With your upload speed, you should NOT be running more than one torrent, two tops.

[µtorrent-Guest]

Firon, I love your ability to say things with these clear english words: plain, short and right on the spot! :-)

may i have a question?

observing some strange behaviour with my queue lately. (build 456 right now)

What are EXACTLY the differences between the values:

Maximum Number of active torrents (upload or download)

and

Maximum Number of active downloads

the advanced setting "do not count" values are still 1 kb, aren't they?

[j_rivers]

Your upload bandwidth is MAX to 160/8 = 20KB ~! So , After you start seeding some torrents , maybe the upload bandwidth is reduced to 2 or 3 KB free .....So It does will suffer your Browsing the web pages ~!

[foussais]

Many thanks to everyone for the replies - I understand the situation a lot better now - I had overlooked the upload overhead created by the simultaneous downloading.

I tried the download suggested by uTorrent-Guest, and I was staggered to see it download at 128kbytes/s - I didn't realise it was possible to download at that speed!

Thanks again, and best wishes to all...

[Firon]

µtorrent-Guest: yes.

foussais: I suggest you turn off DHT to save bandwidth.
