Speed problems

[ronim]

Here is the problem:

1) I have download speed capped to 1MB/s while i am using utorrent latest versions (stable or beta) - default settings

2) I dont have such issues when i am using utorrent 1.8.5 or bitcomet and i am downloading the same torrent with 8 or 9 MB/s - default settings

3) The upload speed seems to be the same no matter what i am using - default settings

Windows xp sp3 32 bit. Connection patched. I also played a lot with the settings since i do understand quite much what i am doing, but w/o any success. The issue isn't firewall/router based for sure since I played these scenarios and checked them out. It must be something within the application itself. Some of my friends experienced the same problem using win xp sp3 32 bit too. Windows 7 friends does not have this problem. Most of the guys affected by the problem are either sticking to old version of the client or switching to other torrent clients. It will be nice if the problem got solved in the next version.

edit: forgot to mention that all tests are done on default settings.

PS: it is irritating that i have to register to post. Lots of people dont tell about the problems they experienced because of that and just switching the clients.

1. test with ubunto torrent (in my tips/sig)

2. what are your results at speedtest.net ? and what is your connection max UL/DL bandwidth ?

3. Have you applied the "setup guide" recommended settings ? what are they ?

any speedgraph screenshot ? including setup guide dialog with your settings ?

[ronim]

1. test with ubunto torrent (in my tips/sig) - using 2.* utorrent i've got 1.1 MB/s. Using utorrent 1.8.5 i've got 6 MB/s+

2.

3. I did test the settings Ultima suggest in his sticky thread. No gains at all.

my speedgraph is a line fixed at 1.1 MB/s when i am using 2.** and ~9MB/s when i am using other torrent clients. I tested mainly with default settings. I mean just install and try. When i removed the version of the utorrent i used the option "remove settings" so i knew that it is always default settings. And the setup guide was that one of Ultima i mentioned before + some other tweaks i made myself after i saw no gains using the mentioned guide.

[rafi]

Nevertheless - can you list/screen-shot the main settings (setup guide Or also bandwidth+BitTorrent dialogs)? Guessing is not advised ... and you are welcome to have a look at the other tips in my sig ... and not just tale the ubuntu torrent from there...

btw, what is your OS ?

A side-note - I wonder why don't you get close to 70MB/s but only 9...

PS:

all tests are done on default settings.

this is not advised, mainly for such large bandwidth as yours. This is why they invented the setup guide...

PS(2):

PS: it is irritating that i have to register to post

And how do you propose they will get notified if someone answers them, so to look and maybe respond back ASAP ? Press F5 day and night ?...

Well, I see Vuze forum requires registration as well. So I guess your friends choices are narrowing down...

About the OS: Windows xp sp3 32 bit as i stated in the first post

About the speed: I've got 9 MegaBytes/s not Megabits or more

I use the same default settings for old but thrusty 1.8.5 version. Default settings on other torrent clients give me the same speed as utorrent 1.8.5

About the testing things... i tried the 100 mbits settings... no gains. Tried disabling all the suggestions on that guide i mention... no gains too. Tried other suggestions + other things i figured out looking at the advanced tab.. still no gain. It is like the application is capped to allow 1.2 megabytes/s at max. Generally 1.1 megabytes/s. And as i said the problem is spotted at other windows xp sp3 32 bit pcs. Windows 7's pcs seems to lack that issue. Tried some of your suggestions too... not all tough.

About posting... w/o registration but with spam bot.

PS: I posted about the problem because i like this torrent client... so after like a month or two since the problem was spotted i get over my laziness and register to post I solved my problem by sticking to old version but the guys might want to solve it in any future versions. To me, this is a bug.

any speedgraph screenshot ?

???

>i tried the 100 mbits settings

So you should try it again... It should be set so (~9MB/s Upload limit, and even 250 connections/torrent [1000 global] if you run a single torrent)

And read & do what my tips-guide says in B [1] -

"bandwidth->apply rate limit to transport overhead"

Plus - A [1] for your disk cache settings

>About the speed: I've got 9 MegaBytes/s not Megabits or more

you should be getting 60-70MB/sec (per speedtest.net). Your ISP might be throttling you.

[ronim]

well... the speedgraph is like a "dead man" line. That's why i didnt post... will do that later.

About the settings i did tested... Your 0, B and C proposals are all covered up in my examinations.

Bro.. i guess you dont understand me about the speeds i've got. 9MB/s = 75 megabits/s (8 bits = 1 Byte. 2^10 bytes = 1 KB. 2^10 KBs = 1 MB). My ISP did not throttle me for sure. When i am torrenting i surpass the speed i posted in the shot. Of course if i am using a torrent client that can do the job.

Since i have to reinstall the new client to do the testings and then show you the sceenshots and after that redo the things to old versions so i can happily torrenting, thats why i didnt bother to screenshot every possible scenario i did before.

It is a problem of the new client...

PS: As i said... i posted this info because if some other guys have that same issue they should know what they would do until the problem is solved... if solved at all. I am quite happy with 1.8.5 version.

[rafi]

Well, sorry about the speed mixup. For a 10Mbit/s upload you should setup a ~120KByte/sec in the uT bandwidth setup (and not 0 as you have it now) plus ~200 connections/torrent.

Good luck.

Here is the picture: http://img514.imageshack.us/i/oldit.jpg/

Tuned for 100 mbits with the proposed upload limitation. Did second test with 120 ( I downloaded the torrent for second time ) instead of 1200 upload limitation... no change.

First to see is that i get the speed quite slow and never surpass 1.5 MB/s and this is by the way a record using the new torrent client. At the end you can see that the line goes almost straight despite tuned to show even 100 kbit change.

Edit: less seeders allowed and default settings but using:

1) Old utorrent http://img31.imageshack.us/i/oldutorrent.jpg/

2) bitcomet http://img804.imageshack.us/i/bitcomet.jpg/

"I use the same default settings for old but thrusty 1.8.5 version. Default settings on other torrent clients give me the same speed as utorrent 1.8.5"

Did you disable uTP completely in v2.0.3 to compare it to v1.8.5?

What bt.connect_speed and net.max_halfopen values are you trying in both cases? (v1.8.5 and v2.x)

Did you try also disabling IPv6 in uTorrent v2.0.3? (in advanced settings...it may be buggy so you may have to disable IPv6 in windows as well )

"For a 10Mbit/s upload you should setup a ~120KByte/sec in the uT bandwidth setup"

Typo! Rafi probably meant ~1200 KiloBYTES/second upload speed max. I actually think that's a little high, but if your speed test reports ~11 mbit/sec upload then 1200 KiloBYTES/second upload speed max *should* work if your ISP isn't disrupting/throttling BitTorrent traffic. Do note that if your torrents have low demand you may not be able to find enough fast(er) peers to reach your upload max.

[ronim]

So i did suppose.. that it was a typo and if you look the screenshot it is 1200 not 120

There is no logic that my ISP will do anything for just the newest utorrent clients and do nothing to the older versions and other clients.

About the optimal speed... well the torrent in all the cases was the same one. And i usually go to 8+ MB/s in less than 15 seconds. Actually less then 10 seconds.

About the uTP settings...i checked and it turns out that one thing was still on. After disabling it and setting net.disable_IPv6 to true... the speed gets like 7-8 MB/s which isn't the max but still quite a jump. It left me with the feeling of pumping the speed a little bit sluggish compared to the other alternatives but still a nice move. Thank you.

"There is no logic that my ISP will do anything for just the newest utorrent clients and do nothing to the older versions and other clients."

There has been many Russian ISPs (and no doubt elsewhere) that went to great lengths to detect and cripple/disrupt/throttle uTP (UDP-using) traffic by uTorrent. Since v1.8.5 does not make uTP connections by default, it would be mostly or fully unaffected.

ISPs have proven adept at all kinds of Deep Packet Inspection to throttle/disrupt based on all sorts of mostly-unknown and arbitrary criteria. I've even heard of a case where TeamSpeak was getting totally disrupted on 1 ISP in Australia...the ISP of course denied everything, but a couple weeks later it got magically all better for the people on the same ISP reporting the problem.

[ronim]

Well, i am not saying that it is not possible, i am saying that this is not the case. I live in a small city ~ 300K peeps and all guys around here are using the torrent system quite much so it will be a big shout if it happens. Hopefully it wont happen.

[Switeck]

That leaves you with the cause probably being your networking hardware or software...probably just isn't robust enough for uTorrent's levels of UDP traffic. (...and other special connections, such as Local Peer Discovery which may be using multicast if enabled.)

Do you have native IPv6 and/or Teredo/IPv6 active?

[rafi]

yeah, 120 is a typo... be sure to follow B in my tips (like pref.->advanced->bt.tcp_rate_control = false) and , as It & Switech suggest - if nothing works for you... try also BitTorrent->Enable Bandwidth Management = unchecked
