Download speed are always 80% from my total

[nordayd]

Hi,

Since i started to use bitorrent my max speed i could get is only 80% of my total.

Even if i download something with many seeders like from private tracker

the download speed is always remain stable at 80% of my total speed.

even after i changed my isp speed before a half year the max speed in torrent is not 100% is only 80 - 85% (from the new speed).

with 5MB ISP SPEED i get stable downloads at 505kbps instead my max speed 625.

it's look like something is limit my max speed, and it's not in the software i think..

i think it is NOT my ISP that limit my download speed, after some tests i made..

it's help to surf the internet while download but how can i get max speed when i want? it's very annoying.

thanks

a screenshot of your download of ubuntu test torrent can help (in my sig) . Also upgrading to 2.03 might improve your net payload speed.

More tips in my sig..

the ubuntu test torrent download speed is unstable (and don't even get close to 60% of my total speed).

but i estimate that it's normal because it's have more leeches then seeders....

anyway it's not demonstrate my problem because the problem isn't that i download slow

the problem is that good torrent (with many seeders and few leechers) i download fast and stable but 20% less then my total speed

i'ts look like utorrent is use only 80% of my internet because the speed is very stable.... and HIGH but not at my max EVER

thanks

BTW 2.03 is still beta.. i wait to the final version.

Maybe your ISP is to blame? ...because it throttles BitTorrent.

However you didn't list your uTorrent settings...and how close they are to your real linespeed.

@Switeck my uTorrent settings is like as in the speed guide, i also reset my settings and try to play with it and it's didnt change to much.

@rafi it's don't download fast enough that torrent

an odd development:

i find the cause of the lose of download bandwidth is the UTP protocol (Enable bandwidth management)

when it's cheked the overhead is HUGE and is 15% of my total speed.

so i disable it and get my total speed STABLE, after it then suddenly (after i complete download last torrent at max speed without UTP) (without change anything from last time UTP is still off) i can't even get to 65% of my total speed stable.. the speed it's evene not stable

so i tried to enable UTP and very fast 80% of total speed stable and 15% overhead

and try to turn it off so again 65% and NOT STABLE and overhead is very tiny..

after some time with UTP off i can get 80% of my total but NOT stable and tiny overhead

and with UTP i get immediately 80% of my total STABLE with huge overhead

it's very odd.....

maybe my isp is throttle bittorrent without UTP?

someone have an idea why UTP overhead is that big?

from what i've understand it's need to save bandwidth and not to spend it on overhead..

BTW: more one thing i have noticed is that many peers that i download from the download speed is only 0.1KBPS

there is a way to drop that lower peers? because it's only spend that peers connected..

[rafi]

>someone have an idea why UTP overhead is that big?

yes - a bug of using too small packets. It's fixed in 2.03. You'll just have to wait till the world will upgrade...

[nordayd]

you have an idea why wihout UTP the download ar not stable and STILL can't get more then 80% of my total speed?

the first time i disable UTP i get STABLE 100% speed

second time max 80% speed and not STABLE

thanks

[rafi]

No . And it makes no sense to explore it in 2.02 when 2.03 is underway.

[Switeck]

nordayd, most people get settings wrong and I don't know if you're not one of them.

[nordayd]

@Switeck

i just reset the settings to default (delete the settings file) and only changed the connection limit and the default directory.

and of course the total connection isn't to high: 550

per torrent connection: 150

upload limit slot: 2

upload limit: 21kbps (asymmetry connection)

download limit 0 (unlimited)

also try to play with UTP on and off

and that's all.

BTW i also noticed that when the overhead (UTP on) is still high but less then usually the max speed is still at 80%

as if it's not the cause, weird.

[rafi]

It seems to me you didn't read my tips at all... With 20K upload limit you just cannot get to 600K download. You need at least 30K (~5%), and with 2.02 - you'll also need to disable uTP due to it's high overhead.

And good luck!

@rafi

i try to play with this settings before..

didn't help.. now i up it to 35.. same problem..

[nordayd]

it's still don't solve the problem..

if i disable UTP the download are very slow, why?

and if i enabled it, it's fast but look like it's have h 80% limit at download (even when the overhead is not huge)

and of course the total connection isn't to high: 550

per torrent connection: 150

Those are both insanely high if you're only able to upload about 20-30 KiloBYTES/second. You'll probably have very high levels of overheads as a result, if you're on torrents that actually have that many connections.

[nordayd]

@rafi screenshot of what? i gave you the number of connections..

@Switeck i able to upload more than 20-30 kbps but i limit it to lower number because of the huge overhead

i also try to play with it and to up it and to lower it

eventually, i put it higher: 62 kbps

now, ubuntu speed test.. i eventually succeed to get high download speed (80% of my total) after 5 min

but i don't get more then 80% (if the UTP is off i get slow speed)

and the high speed (UTP on) stays not for long (goind down for 15% speed)

thanks

[Switeck]

Lower max connections and per torrent connections and see if that reduces overheads somewhat.

Rafi's guide tells how to force uTP to always use max packet size for data.

Disabling Resolve IPs won't hurt either.
