1.3 doesn't properly connect to peers?

[Jwizzman]

I've noticed that 1.3 doesn't properly connect to peers, after i've upgraded all my torrent were very slow, the client only connect to like 1 or 2 peers sometimes, very anoiying, even on a 1000+ seeder torrent, i've downgraded back to 1.2.2 and this one doesn't seem to have this problem?

what's up with this?, 1.3 is very very very slow

I can't seem to reproduce this problem. :/ Just for you, I tried this on a massive 1200 seed/4600 peer torrent, I set peer amount to 100 and with my miserable 128kb/s upload I was able to reach that amount in about 5~6 minutes and stay connected... :|

[Jwizzman]

right now, there's this torrent with 11 seeds and 34 peers, it downloads fine with 1.2.2 but with 1.3 it won't even start, ocasionally I get something under 1kb/sec but mostly nothing

Lower the value in bt.connect_speed (try 16), sounds like it's overloading your adapter/modem/router.

[1c3d0g]

Hmm...interesting. Are you sure you have everything set up properly? You know, port forwarded, Network OK, down/up capped at ~75%, etc.? :|

[ironboyzz]

Similiar Here!!!

Yes slow connects overall but seeds in my case as much as 30 mins...sometimes torrent is finished by time connect to 1 and sometimes never! Timestamped 27mins to connect to seed of 9 with 2 other peers leeching.

For notation: DHT is disabled and have been using BW alloc heavily... tops 3-5 torrents runnning! Nominal bw being used!

Edit: Will try lowering conn speed to see if helps but don't think that since not prob prior rel.

ironboyzz: does the rest of your internet slow down too?

[ironboyzz]

If it is, I'm not noticing or feeling it so nothing to speak of! Have a 10/1mb conn so maybe wouldn't notice?!?!?

Tried the connect speed but no change.

First thing I noticed is peers come before seeds (fairly normal)...but in one case had to wait (15 mins) for peer to connect to dl when I was the only/first lch. These were low s/l counts so easy to watch..1-9 sds , 0-3 prs. First thought it was a tracker issue but jumped to another and similiar. Then thought the BW Alloc options but set them all to normal.

Ludde said the upload was more aggressive so maybe in changes the polling loop/thread falls out or never gets in based on initial start...something like that??? Given looking for net slow down assuming looking for indefinite loop symptom.

Anything else I could look at??

Are you on SP2? Did you change net.max_halfopen? Did you patch TCPIP.sys? If not, patch it to 100 and try raising net.max_halfopen (read the faq)

[ironboyzz]

sp2, patched, half-open 8 tried 16...this has been status quo.

[Firon]

By the way, did you restart µT after setting bt.connect_speed to 16?

What did you patch TCPIP.sys to? If 100, try setting your net.max_halfopen to 70 if bt.connect_speed still does nothing. (and maybe set it back to default)

[ironboyzz]

Yes on restart...reboot, reset router/modem, Yes to 100 ... will try halfopen 70

[spriseris]

what kind of router? i'm starting to believe router is the #1 reason for crappy torrent performance.

[Firon]

If it's a WRT54G/GL/GS... read along. http://utorrent.com/faq.php#Special_note_for_users_with_Linksys_WRT54G_GL_GS_routers

[ironboyzz]

its a WRV54G with latest patched FW, Used it for the 2+ yrs.

[spriseris]

what's the difference between a WRT and WRV?

[1c3d0g]

I think it's something about VPN, to communicate securely to your Office's network, or something like that... :/

[ironboyzz]

"U", jaj!! Its a VPN Router!! Virtual Private Network!

Just to let you all know, went back 122 for now ... needed to finish seeds and should be able to revisit tonight!!

@Firon> Anything else you want me to try/look at??? Have already planned some testing torrents...was wondering if you or ludde had a test tracker to check from your side!

[Jwizzman]

Is there anything that signifigantly changed in the way connections are made? (from 1.2.2 -> 1.3)

[1c3d0g]

Not to my knowledge, only the upload was made a little bit more "aggressive". :/

[ironboyzz]

Hey All,

Went back to 1.3 and disabled UPnP ... that seemed to work as far as connecting speed but still have problem connecting to avail seeds/peers ... e.g 50/8 avail > 3/3 connected ...

Settings:

DHT disabled private trackers

Glb Max conn 1000

Max conn per trt 30 \

Max ul slot per 15 / even if I upped these same

halfopen 64 (upped per Firon)

connect speed 30

lazybit true

low cpu false

****

Think may have hit on something else.... seem to have problems with torrents that have private tracker bit off. In fact the example above is from trt with bit off.

Edit: connections come on and off...does clock ul/dl ks

****

Edit2: After 2hrs above example as climbed to 54/13 avail > 6/3 conn

Edit3: New torrent with PT bit on 2/14 avail > 1/9 in a couple of mins. cranking speed for this one also 400+dl / my max up stat bits UD or d through all conns

Check Edits from my prior!!!

With changes I did, a torrent I tried 2 days ago, which sat for 1hr without getting a seed on first attempt, started and connected in seconds!!!

Hi together.

I've noticed the same problems as ironboyzz and some others. I opend a Bug in the Bug Forum (see here -> http://forum.utorrent.com/viewtopic.php?id=3483 ). I will try the settings of ironboyzz to see if its better working. I am releasing new torrents so using µtorrent for this is currently unacceptable. I will edit this Post when I got the first results.

Edit1 ~ My current settings:

I have a DSL 6000 which means about 80kb/s upload and up to 650kb/s download.

My router has NAT enabled and forwards Ports 65509. Previous versions worked much better. With previous versions I mean 1.0-1.2 beta builds.

Actual example:

Torrent with 13/17 (seeders/leechers). Connections 5/4 (seeders/leechers).

Same torrent in Azureus:

Connections 11/14 (seeders/leechers).

Edit2 ~ Disabled UPnP:

- Didn't change the result.

If you need more informations please leave me a PN. I will add as much info as need to solve this bug.

Best regards,

[ironboyzz]

@ ShAQ> Disabling UPnP help my torrents speed up in connecting to s/ps not so much as the number of connections overall.

Edit: Since I made my changes, have not had any problems on my side...granted there are many factors as to how/who you are connected to, but for the most part, everything is working as I would expect it to.

TBH, I think my problem is an issue with µTorrent, Windows and Firewall collectively using UPnP. Other than disabling UPnP on µTorrent, no other changes were made. But note that all was fine with prior versions!

@ ShAQ>[...]But note that all was fine with prior versions!

And thats the point. I didn't changed my settings.

With 1.2.2:

- Fantastic Speed

- Fast connection to others

- upload is stable

With 1.3:

- Slow Speed

- less connections to others (extremly!)

- upload is a little bit unstable

Please keep in Mind - I didn't changed my settings or replace anything on my hardware or somethings. Just a simple version change, nothing more. But with extremly effects ...
