rafi Posted September 18, 2010 Report Share Posted September 18, 2010 -- 2010-09-10: Version 2.2 Beta (build 21882)- Feature: end to end path MTU calculation based on ICMP messages and missing packets- Defining 10 UL slots, reaching 4-5 slots - MTU is fixed/"stuck" @ 1444 bytes (like 2.04)- DF flags are all set to defragmentSee for yourselves:http://img198.imageshack.us/g/73347555.png/capture: http://www.mediafire.com/?zrvwcqc3cexhjbfDid anyone really tested seeding with this release ? ... Checked that all back-ported features (from 3.0) really do work ? Back to 2.04 . Let me know when it's tested and working. You know my email... Edit:And if you did test it on the latest 3.0 and it DOES work there- let me know as well. Thank you. Link to comment Share on other sites More sharing options...

rafi Posted September 18, 2010 Author Report Share Posted September 18, 2010 That was to see if anyone do really read those posts/results... typo... thanks Link to comment Share on other sites More sharing options...
Switeck Posted September 18, 2010 Report Share Posted September 18, 2010 Seeding not reaching max number of upload slots is working as designed...even though that does have its weaknesses:http://forum.utorrent.com/viewtopic.php?id=45733 Link to comment Share on other sites More sharing options...
rafi Posted September 18, 2010 Author Report Share Posted September 18, 2010 I see. Confusing... Thanks Link to comment Share on other sites More sharing options...
Switeck Posted September 18, 2010 Report Share Posted September 18, 2010 Caused by:http://forum.utorrent.com/viewtopic.php?id=3474A different upload approach Link to comment Share on other sites More sharing options...
rafi Posted September 18, 2010 Author Report Share Posted September 18, 2010 Just discussed that with alus on IRC... He'll have to clean up (delete) all the settings for that #. Pref->bandwidth, properties, setup guide ect... Maybe just display it somewhere .I guess just writing the code w/o modifying the related UI - is not enough...

Switeck Posted September 18, 2010 Report Share Posted September 18, 2010 You mean removing user-configurable Upload slot limit?! Link to comment Share on other sites More sharing options...
rafi Posted September 18, 2010 Author Report Share Posted September 18, 2010 Yes (as I understood - it's all global and automatic now). Though personally I would like to have some global control over it, it IS one less item to bother the simple user with... May be a global setting with default - 0 (=auto) can be best.btw, people do report on problems of low UL speed in the 2.2 thread... so I guess alus might have still some tuning to do Link to comment Share on other sites More sharing options...
Switeck Posted September 18, 2010 Report Share Posted September 18, 2010 Whether it's in normal settings or advanced settings, I don't care.But I do care if it actually works.I'm seeing too many upload connections running at <0.5 KB/sec, both from distant sources or even sometimes from my end. This is often caused by uTorrent's behavior rather than ISP throttling.Torrent priority probably should affect it -- no point giving a torrent set to "LOW" a lot of upload slots while one set to "HIGH" also has lots of peers you could upload to.

rafi Posted September 21, 2010 Author Report Share Posted September 21, 2010 Well, we can discuss/re-test seeding after the UI/setting for the new chocker will be revised to set a global max. On the main issue - PMTUD - here is another test:- My MTU was set to 1392 (on my PC/NICs)- seeding 1 torrent in uTP/ V2.2-uploading to 3-5 peers (mostly v2.04 peers)expected result - un-fragmented packets of size a bit below my set MTU Result: packet size reaches 1402 (1410) and the DF flag is not set, showing - that packets are still being fragmented (my guess: 1402 + 42 = 1444 ...) On some peers - the size did drop to ~762 (not-frequented). But - 2 packets of 700 + 700 are like 1400 + 40 as far as PPS goes.... So, I guess they should all be decremented and by smaller steps/decrements. When you did this simple sanity test, what were your results ? screens: http://img841.imageshack.us/g/42821809.png/capture: http://www.mediafire.com/?4llfbuzxurdyu1yMy conclusion - it is broken...

Switeck Posted October 19, 2010 Report Share Posted October 19, 2010 More details concerning low seeding speeds and poor upload slot use ...with screenshots here:http://forum.utorrent.com/viewtopic.php?id=84906 Link to comment Share on other sites More sharing options...
rafi Posted October 27, 2010 Author Report Share Posted October 27, 2010 One more test: This one starts with a single torrent with 5K/10K/20K/25K/30K upload limit. It continues for ~10 hours with the 25K limit. Using uTP + TCP.On the way - RSS added two more downloads, that had about 2.hours download and 1.5 hours seeding each ... Screen-shots:http://img153.imageshack.us/g/ulslots25knetoverheadre.png/Full log (16M, sorry, 400M unzipped):http://www.mediafire.com/?fk8e7c442yf239yBottom lines:1. # of slots are (with 1 torrent): - ~9 @ 5K- ~8 @ 10K- ~11 @ 20K- ~8 @ 25K- ~4 @ 30K Peers-connections are having 0.6-3K speed when speed is <25K - too low speed/slot , and too many slots/UL speed.I think there should be a set limit of >4-5K/slot and >3-4 slots / torrent. Also 0 the actual UL limit should be taken into account!2. The is a strange drop every 5 minutes, with retransmit overhead. You should find the cause of this (not sure if it is the choker itself)3. Totals are good here: 1.03G uploaded, 2.18G (= 3.22G) downloaded - Data pnly1.1G uploaded , 2.3G (= 3.50G) downloaded - Data+ overhead (traffic cap)~10% overheadSo, tuning 1 , and finding the cause for 2 will do nicely for a release of a good and easy to use choker Other tests @ a connection with higher speed are desired.
