Comments on: Testing µTP – is µTP actually faster than regular BitTorrent?

I have been using uTP without knowing it and have not noticed any difference either way as all files download at wildly different rates for various reasons anyway.
Whilst I cannot completely understand all of the tech stuff, the broad concept of uTP sounds good and makes sense. A bit like slowing cars on a motorway where traffic ahead is dense to prevent being stuck in a traffic jam? Would you agree Simon?
I am a great fan of uTorrent and have been using this free software for many years. It is a shame when people put a lot of effort into trying to improve stuff for others and get rude comments on forums like this. Unfortunately this is all part of life.
Constructive criticism should surely be welcomed by all, but there is no need to be rude.
I think you guys at uTorrent are doing a great job, keep it up.

Hi. Myself being not the most Comp’ Tech’ literate individual I have a question RE: the uTP vs. TCP. What it is I have to ask may have already been answered (in one way or another) in the above article and/or the comments although it is one of the (above mentioned) comments in particular which has served as (an extra helping of) confusion for myself (to an already ‘it’s all greek to me’ type of scenario, as long as it’s downloadable and only requires a few basic modifications to get it running i.e. uTorrent, I can usually figure it out over time by trial and error but otherwise …). Having said that I am rather intrigued by what I’ve read thus far concerning uTP vs. TCP and My Question relates to the following: I am currently running uTorrent 2.2.1 and read else where that, “µTP is a new lightweight BitTorrent protocol used by µTorrent starting in µTorrent version 2.0″, although above I noted the following, “…. so you’ll have to downgrade to anything below 2.0 to connect”. So I guess what I’m trying to ask is 1. Does my version 2.2.1 already contain this uTP concept (by default, and therefore I need not do anything)? 2. If ‘No’, can the uTP be applied to version 2.2.1 (and if ‘Yes’, How? and if ‘No’, which version do you recommend). While I have you on the line (so to speak) one more question (or 2) if I may, 1. I am connected via Phone Line (Broadcom NetXtreme Gigabit Ethernet, I am unsure of the specs’ to share concerning such so I include this (above) in hopes that it relates some nec’ info’ to you) and when downloading a (1) Torrent (Movie) my avg’ speed is apprx’ between 110-128 kB/s (unless during the wknd and prime-time then drastically lower). Is this a respectable speed? My question 2. relates to the previous question by way of my stated avg’ speed when downloading, however it’s specific to the fact that no matter if I’m downloading 1 Torrent or 2 or 3 at a time my ‘Total’ Speed (kB/s) will never exceed this (max’) avg’ of 110-128kB/s (and the same tends to go if downloading only 1 and the upload is reading (say) 50kB/s, such would then limit my dwnload spd to (around) 70kB/s for again a avg’ total overall kB/s of 120ish (now I know I can limit the upload and thus remedy that certain situation in that manner but I don’t like limiting peoples ‘efficiency’ (unless such is generally nec’ and widely employed and I’m just not aware of these types of ‘mannerisms’)) and also that remedy does not apply to my scenerio including multi’ simultaneous downloads, also I have my Preferences Max’ Download (and Upload) set at ’0′ aka Unlimited). Now myself not being overly fluent in this type of stuff I don’t know if my numbers are typical (in which case I am perfectly happy with them) or if they are dreadful and you may be able/willing to kindly direct me to 1 or 2 remedial approaches towards bettering (is that a word?) my efficiency. If by chance anyone has hung in long enough to get to this point in my novel I truly do appreciate your time and consideration and would be most grateful for any advise that may come my way. If the length of this is viewed as unacceptable I do apologize (another lesson learned) and, should you be willing to speak to that which I have enquired about albeit without breaching the ‘comment length boundaries’ (as I may have done), please feel free to email me at ether04@hotmail.com
Again, Thank You Kindly!!!

About speed, this last download my top speed was988kb/s(not avg.)I got 18gigs overnite.
that’s not bad.
Although it may have alot to do with the site.
I don’t know, I’m a novice(begining to learn).

I just recently switched to trying uTP in a Linux-based Torrent program. Interestingly, a torrent I had running at the time that was extremely slow and had found very few seeders suddenly found MANY seeders after switching to uTP. The conclusion I gather from this is that at least some torrent programs are using the uTP protocol exclusively.

Second, I for one really appreciate uTP’s ability to back off when other programs are trying to use the network… as it means I don’t see lots of lag or have other household members complaining that “the internet is really slow”.

Third, from an engineering perspective having Torrents work over connectionless UDP makes a whole lot of sense for both throughput and connection latency reasons.

Bottom line is that uTP is an all-around win, IMHO.

I don’t feel the changes

I personally did not have any hesitation to install V 2.0.3 ( had not updated in a while ) especially after reading about uTP ;
How ever after installing I suffered a dramatic cut down in my DL speed.

I have read through the previous comments to see if any one had a similar problem, I then turned of uTP to see if I had any improvement.

How ever the speed did not change. I am from NZ and I can imagine that could be a specific reason but im talking about a 75kb/s drop on a already ridiculously slow DL rate. I was just wondering if anyone had any advice for me?
It would be gladly appreciated seeing as I don’t want to be slower than I already was.

I was hesitant to update from uTorrent 1.8.5 while the 2.x was still freshly released to avoid the bugs. Now that I have updated uTP has noticeably improved my peer connectivity.

However, it was noticeably slower in its default setting and did more than halve my average speed. I changed bt.transp_disposition to 5 as suggested above and my download/upload speed went back to normal but with the increased connectivity. Seems uTP doesn’t handle my slow mobile connection at 28 kB/s down and 11 kB/s up with average 250 ms ping.

Overall I would say I am impressed and optimistic to the new protocol.

hi Eduard – as a matter of fact we’d disagree with you on this one – uTP is designed to increase the AVERAGE speed at which you download by eliminating the crazy stop-start that happens when networks which rely on TCP get congested and then un-congested. That is the *design* at least. As we are finding out, the internet is a very diverse place and there are certainly edge cases where TCP works faster. We’re making changes to accommodate more and more of those edge cases. If you want to test the difference then its easy enough to switch uTP off – just go to the BitTorrent preferences and deselect the “Enable bandwidth management” checkbox.
Better still, if you discover some issue then please post details about it in the forums on uTorrent at http://forum.utorrent.com so we can improve things for you.

µTP can’t speed up your torrent-client. It’s impossible by design.
If it don’t improves your upload speeds, how this can improve others downloads?

Yes, µTP can improve your bandwidth control, so other application, that require own traffic, can run smoother, but you NEVER get your bittorrent speeds better with it. Noway.

So, placing words “µTP” and “speed” in one sentence is bad idea.

To get things clear, I wrote about this article, not about µTorrent team work overall. But I’m very sorry about µTP creation. µTP is designed to create work for µTorrent team. =:} If you need SPEED, you DON’T need µTP. Definitely.

P.S.: µTorrent 1.7.5 is greatest bittorrent client ever!

I totally agree with your idea. There should be a big button to switch it on and off easily.
