superbizho: A BSOD with tcpip.sys indicates bad networking drivers. Update your drivers. If that doesn't work, make a new thread with µT build number, network adapter being used, if it's a wireless, and your ISP. Also make sure you are configured properly, no YouTube settings. Configure using #1, and if you still have issues after configuring with #1 and updating your drivers, try the conservative settings in #2.

@ bt.transp_disposition = 15, XP SP2, ADSL 1.6Mbps/160Kbps ,2 DL tasks 1 seeding task, 2 slots per task, calc_overhead = true

- download limiter is still broken in here ... :(

- upload speed (measured with external tool) is still above the UL limit (~200 connected peers, calc_overhead=true)

- clearing of the main listview on download click in the RSS view - is still happening

Thanks for the 14981.

Since uTP is now optimized for "full" MTU of 1500, any directions about tweaking Win AFD's FastSendDatagramThreshold value ? Is default 1024 ok or can be optimized for 1500?

And so, FastCopyReceiveThreshold ?

Thanks again. GREAT NEWS, DEP finally!

Any tips on how I can reproduce this? Does it happen when uTP is disabled (bt.transp_disp = 5)?

It's been working perfectly for me since this fix, any hints would be appreciated.

Well, I can see that a few other users have reported the issue, most with ADSL and low UL (maybe this is the case the issue manifests itself more) . What I can suggest for you is to try the same configuration (I'll email you my dat files) and focus on low UL limit (~10-15K). Make sure you measure with some external tool .

AS for the test conditions: 2 DL tasks and one seeding task with ~3-4 slots was enough to cause it. Make sure you have a popular torrents (~1000+ peers).

It was no effort at all to "break" the DL limit. with the UL limit - it was more "difficult" to see it on the speed graph, but you could see it easily with an external tool.

I guess we can count on the the report you had in the 1.8.3 thread that with TCP it performed good, but you are more interested in uTP , right ? ...

I can only point out one more thing, that in my case - I am behind a NAT and had to change the external IP with my ISP ( actually switch to another ISP) a few times during the download. Maybe it is related.

good luck!

hharis:

last night with new 14981 i set net.calc_overhead to false;

uploads are good.

Yes, same here... I think you are on to something... here is what I get with one torrent downloading:

When I start a torrent DL with calc_overhead - true - DL limiter fail to work correctly (also if I turn it off afterwords). Only when I turn it to false AND ONLY then start the torrent - it works... :)

Pay attention also to the fact that the UL shows a big overhead and drops almost the full 10K I allocated when the DL is only 50K ... :(

edit:

also - with trans_disposition = 5 - all is well... so, as expected, it's the new code that should be blamed...

Using 1.9 14981.

For the bt.transp_disposition setting.

1 - outgoing TCP

2 - outgoing uTP

4 - incoming TCP

8 - incoming uTP

Specific combinations:

255 - both TCP and uTP, incoming + outgoing (future-proof setting, always will mean this)

15 - both TCP and uTP, incoming + outgoing (default)

Right ?

So if I use 28 in the bt.transp_disposition setting, I should only get uTP connections, right ? When I'm using 28, I get uTP AND TCP connections... To get only uTP, I have to set it to 10. What I'm I doing wrong ?
