WTH just happened to Utorrent users ?

Maybe they didn't expect that settings they've fine tuned to their exact preference suddenly wouldn't work without any proper warning? Maybe they didn't expect that sudden jump in overhead by features being turned on as default while still being far from ready to use?

Maybe... If they were paying subscribers to the software... (un)Fortunately, it's free. So your expectations are too high... :P (and I do agree with you in principal! look at some other posts of mine...)

Still, a 2.0 user that upgrade to 2.0x (with mostly the same features, but some different settings) that did implement the upgrading-tips, cannot expect a magic fix, unless he provides more details.

Is there any comprehensive listing of what setting defaults are changed and what features are introduced/removed in each build or version? Simply informing properly would most likely have caused a lot less traffic and dissatisfied users.

looked at the change logs ? having users mess with advanced setting is bad to start with . Any release that will not perform well out of the box (default advanced settings) , is IMHO, not mature enough.

For 2.0 RC3:

- Change: Disable net.calc_overhead by default.

Then no mention until the 2.0.2 release where it says

- Change: disable net.calc_overhead by default to improve speeds for users with low caps

So that this setting had issues was, from this, not something new. Providing the information that it's changed could have saved people a lot of trouble. Also this doesn't solve any issues caused by net.calc_overhead, it just hides them. And from what has been repeated many times in threads here hiding an issue is not a solution.

right, they screwed up in the 2.01 changelog... :( And they should have issued a proper message on what the user should do upon update to 2.01l.

This setting does not have "issues". The users that are using it - do... :P The only requirement for it to work properly is to re-adjust the UL limit per the setup guide. And even this was too hard to do for some poeple... :(

Well, you're sort of right that the setting itself doesn't have issues. µTP does, and starting to count in the huge overhead caused by it was doomed to fail. And users always have issues, which is why documentation should be given and written for lowest common denominator. Especially for a piece of software which is as widely used as µTorrent.

I agree . uTP amplified the problem of overhead. So the uTP overhead should be dealt with... not calc_overhead... :P And, as I said myself documentation is needed, also in form of notification on update. Better yet - auto adjustment.

Here is what I proposed to the devs (with no response):

1. Upon update you can check the current value of the calc_overhead + the current uT version #

2. If the value is true (same as you want to update to – you do nothing else

3. If the previous value was false (or the uT version default was false) you proceed as follows:

a. Check if there is an upload limit at all

b. If not – do nothing more

c. If there was – scan resume.dat for all the torrents dated say, from the last 30 days, in general->average-upload/download-speeds, and find the maximum upload and download speeds

d. Make sure that current upload limit is larger than the actual UL speed + 5% or 15% of the maximum DL speed (depending on the transp_disposition value – TCP or uTP as well)

e. Adjust the UL limit to that value if required

4. Notify the user if there was a change made

Also, if there is any download speed limit set- do the same to it as well.

I set net.calc_overhead back to true.

Had my upload speed set to 10 kB/s from a previous upload, that I was sharing bandwidth with another client, on another torrent.

Started a new torrent download, and the download speed shot up to what I was used to seeing. I have it set at unlimited, and usually get 175kB/s.

Experimented both lowering and raising the upload speed and had a drop in download speed both directions. Reset upload to 10kB/s and download speed returned to what I had started with.

My upload limit is supposed to be 22kB/s according to the speed guide.

What's interesting is the upload speed is about 1.5 and the overhead is 8.5 kBs/sec. Of, course as they fluctuate, so does the download speed.

So after all of that, I guess the point is set your upload speed to about half of what the speed guide recommends and see what happens. :)

@WLS: I really doubt that your result will be good for the default setting of using TCP + uTP . It may be suitable for TCP only (~5% of the download speed) . I still believe in the numbers at B in my tips' guide... (btw, I renamed it to "...2.0.X..." ... )
