uTorrent 2.0 SLOW

[elbeasto]

Ever since updating to 2.0 via the last version speeds have been terrible...

What is going on?

I left everything as default except those settings which require change for port forwarding....

Please don't post asking for settings, I've already given enough info.

Thanks

[Marwell]

Maybe I have a solution. The problem is poor implementation of router UPnP. Now I turn off UPnP on router and in uTorrent preferences and manually forward ports. It seems that this has helped.

Read http://www.utorrent.com/faq/network and http://www.portforward.com/

uTorrent's default speed settings are *EXTREMELY BAD* for most people.

That's why we ask for settings.

Also, uTP in v2.0 seems a bit "much" for most crap software firewalls and routers...which unfortunately seems to be far more common than not.

1st and 2nd links in my signature.

I'm sorry Switeck, I've been searching these forums for hours, changing everything possible, and I've seen you post this as your solution before, but those first two links don't really fix my problem. I'd really like to know if they fixed elbeasto's.

Here we go:

I have set up my connection, even using your conservative settings.

I have a green network status light.

Firewall is fine.

Glasnost says I'm not being throttled.

I've correctly used UPnP and now on Marwell's advice, used manual port forwarding.

Changed net.max_halfopen to 4.

Disabled uTP.

Disabled DHT.

peer.lazy_bitfield is enabled

I'm running a fresh install of Windows 7. I was using utorrent earlier today and getting great download speeds. I just installed a new os on a new rig and now, maybe the 2.0 update has something to do with it, i'm getting an average of 40-50kB/s down. The speed tester puts me at 20Mbits down and 6Mbits up. I've gotten 1MB/s on downloads from websites. I am thoroughly perplexed. I'm not sure you can help, but I needed to rant.

Thanks in advance.

[Switeck]

Just saying you used my conservative settings...doesn't tell me what your settings ARE.

Are you sure your line can sustain the upload speed max you told it to use?

[glowcrit]

i also have a very similar problem, i have been using utorrent for years, port forwarded, stock standard settings getting downloads at 500+kb/s as soon as i installed 2.0 my speed wont rise above 50kb/s, i have a green light stock settings have worked perfectly for me for the last 2 years, i had to uninstall 2.0 and install 1.8.2. its a pain coz every other time i open it its auto updates to 2.0 s o i have to uninstall everyday, need advice

[DreadWingKnight]

Provide the information our troubleshooting guide requests.

[ozmian]

I just installed an older version and my speed is back!!

I'd advise you to do the same...

[Maravis05]

I don't know if you can see that... anyway, while I download my up cap is 5k. then I let the upload max out when I'm done.

Also, does anyone know a good place to find older versions?

[DreadWingKnight]

You missed preferences - queueing, although your upload rate should be better tuned for your connection than just a blanket 5kbyte/sec.

Also, does anyone know a good place to find older versions?

We don't support that.

[Maravis05]

... okayy. I'm only trying to download one torrent, and I don't see how limiting my upload to "a blanket 5k" is going to affect my dl speed. So...?

[DreadWingKnight]

5kbyte/sec divided by 8 upload slots per torrent

and you wonder why your speeds are pathetic.

[Maravis05]

Because my router can't handle 8 connections at less than a k each? Because my ISP can't handle upping at 5k? Because my hd can't handle reading five kilobits a second? I let my upload rate go and I uploaded near my max of 588kb/s and still downloaded slowly. You may never have claimed to be nice, but why moderate a board if you're just plain going to be grating? Computers don't need to do math with integers. I don't see why just because you have a problem dividing 8 by 5, you think a transistor that does simple calculations in the billions per second should. Have a good weekend, and have your cal hw done by monday.

[DreadWingKnight]

Because you're uploading at less than 500bytes/sec and people's clients flag you as an ungrateful leech.

Uploading too much chokes off your connection's ability to acknowledge and request downloads.

I'm grating because people like you NEED to be grated to get the point across.

Perhaps this will help:

Set the bt.transp_disposition value to decimal 10.

Explanation:

µTP (uTP) or micro Transport Protocol is a protocol used by bittorrent client. This protocol aims to reduce latency and maximize bandwidth when the latency is not excessive. While normal bittorrent traffic uses Transmission Control Protocol (TCP) to transfer data, bittorrent client that supports uTP is able to transfer data between clients using User Datagram Protocol (UDP).

uTP is supposed to improve bittorrent traffic (uTP can possibly avoid traffic shaping) and you should see improvements in your bittorrent download/upload speed when most of the peers use uTP. So far uTP is used by uTorrent and official bittorrent client.

The bt.transp_disposition value will let you control how uTorrent uses normal TCP or uTP for data transportation.

The bt.transp_disposition value is interpreted as a bit field and you probably need to learn binary to understand it.

As this post is written, the latest uTorrent 2.0 beta build 16666 accepts these values:

1 – allows uTorrent to attempt outgoing TCP connections

2 – allows uTorrent to attempt outgoing uTP connections

4 – allows uTorrent to accept incoming TCP connections

8 – allows uTorrent to accept incoming uTP connections

16 – tells uTorrent to use the new uTP header. This is an improved communication header, but is not backwards compatible with clients that do not understand it.

Basically, these values can be added together in order to enable the options. Examples of bt.transp_disposition values combinations:

31 (16 + 8 + 4 + 2 + 1) = enables all the options above

15 (1 + 2 + 4 + 8) = uTorrent will attempt both TCP and uTP for outgoing connections, and accepts TCP and uTP incoming connections

10 (2 + 8) = uTorrent will only attempt to create uTP outgoing connections and only accepts uTP incoming connection

5 (1 + 4) = uTorrent will only use TCP for outgoing connections and when accepting incoming conncetions

The default bt.transp_disposition value for uTorrent 2.0 beta is 15. Setting bt.transp_disposition value to 255 will guarantee to enable all options including future options. bt.transp_disposition can be accessed by navigating to uTorrent's 'Options' menu > 'Preferences' > 'Advanced'.

Thank you Marwell. Awesome post.

Dreadwing, I apologize for being juvenile. I am not the type of person that needs to have things explained in a harsh manner. What you said in your second post makes sense, but it would also have made sense to include that in your first post. I will take that into consideration, and I would like to add that I let all my torrents seed until the ratio is 1.5. I just download and seed at different times, in the past this helped me achieve high download rates. I suppose I may have to change this habit.

[Marwell]

Awesome post? - Only did "Copy" and "Paste".

By the way - did You try turn Your computer off and on again?

[pkrisnin]

Yeah I sometimes experince almost zero speed after the upgrade, been using using it for several days.

so when encounter this slow speed session I did a test to downgraded back to version 1.8.4 and speed went back to normal.

So something is wrong with the latest version of 2.0. I'm thinking the uTP is reading false positive of network congestion.

[DreadWingKnight]

I'm pretty sure you need to provide more information than that you tried with an unsupported version to make me believe you.

Especially since I max speeds out on my system using 2.0

[pkrisnin]

I'm not saying it happens all the time, only certain times.

current version I downgraded to is 1.8.4 build 16688

[Switeck]

BitTorrent works on tit-for-tat, you give to get.

Other peers not only will upload to you slowly if you give to them slowly...they may refuse to upload to you at all! They instead will reward the peers that give them more. This is intentionally by design.

What it means is you need to give at least 2 KB/sec PER upload slot to get reasonable download speeds back...unless the torrent is almost entirely seeds.

[ABCStore]

Setting bt.transp_disposition to 5 took care of the problem for me.

[RobinRichard]

Try the new beta.. It solved my speed problems... µTorrent Beta (2.0.1 build 18284)...

[Marwell]

Yes, new beta is a little better.

[Venge_75]

Same problem here..upgraded to 2.0 and things started going very slowly. Went back to 1.8.5 problem solved.
