WiseguyNL Posted May 9, 2009 Report Share Posted May 9, 2009 I'm having a strange problem with Utorrent lately. It doesn't occur all the time and it's not torrent-specific. Here's the speed diagram: As you can see, every 30 seconds to 1 minute(the time varies, often it's every 5 minutes) the speed drops to 0 and then jumps back up to it's regular speed, basically cutting my actual speed in half. I'm on a 100mbit up/down internet connection(Onsnet Eindhoven, the Netherlands) with a Sitecom WL-306 (wired) Router. All my ports are forwarded properly. My firewalls are all disabled. Another question: Why are some torrents much faster than others, even though the seed/leech ratio is much lower? Some torrents download at 4.0 Mb/s, while others struggle at 50 Kb/s, even though they both have healthy ratios and plenty of availability.

jewelisheaven Posted May 9, 2009 Report Share Posted May 9, 2009 General speed inconsistency is reliant on peers' decision to upload. With enough peers I guess you could keep it constant but it would be a burden on your end to keep making so many. What Ctrl-G (Speed Guide) settings are you using?The graph brings to mind some changes made recently to the new line, what version of uT are you running? Would you be willing to run a beta version to see if it makes your downloads more even?OT: It is never a good idea on a Windows machine to be on the Internet unfirewalled but your sitecom router acts as a hardware firewall which you probably already knew Link to comment Share on other sites More sharing options...
Switeck Posted May 9, 2009 Report Share Posted May 9, 2009 The graph looks like your download is falling all the way to 0 briefly.That's most like some serious network issues.Many consumer networking hardware and software CANNOT handle lots of connections at once.1st link in my signature.

WiseguyNL Posted May 9, 2009 Author Report Share Posted May 9, 2009 The speed doesn't go all the way to 0, it goes to about 5 kb/s. I haven't changed any settings recently and a few weeks ago I managed to get 11.5 Mb/s, so I guess my networking hardware should be able to handle it. My current settings are actually lower than the recommended settings in Utorrent for 100 mbit, becasue I like to be able to still browse the web while running utorrent. Here they are: Upload limit: 1000 Kb/sUpload slots: 30Connections (per torrent): 125 Connections global: 1000Max active torrents: 25net_max_halfopen is at 160 (and patched properly on Vista) My computer has been awfully slow lately. Could it be a harddrive problem, instead of a networking problem? Link to comment Share on other sites More sharing options...
DreadWingKnight Posted May 9, 2009 Report Share Posted May 9, 2009 net_max_halfopen is at 160And what gave you the delusion that this is a good idea? Link to comment Share on other sites More sharing options...
jewelisheaven Posted May 9, 2009 Report Share Posted May 9, 2009 To answer the question though, your settings are the first place to start. Use sane values from Switeck's #2 link. Link to comment Share on other sites More sharing options...
Switeck Posted May 10, 2009 Report Share Posted May 10, 2009 WiseguyNL said, "net_max_halfopen is at 160 (and patched properly on Vista)"Did you check to see that Vista isn't getting lots of 4226 errors because of that?Vista's half open limit would need to be 200 or more for uTorrent's net_max_halfopen to be set to 160. ...But it's really pretty pointless to set net_max_halfopen that high if uTorrent isn't firewalled (has the green light.)jewelisheaven, for 100 megabit/sec upload settings...my chart is even more "insane" than uTorrent's Speed Guide xx/100Mbit!

jewelisheaven Posted May 10, 2009 Report Share Posted May 10, 2009 Oh-wow! Indeed. I really never looked past 5Mbit, eye fatigue you know But the settings certainly aren't helping as on 100Mbit down to not sustain 1 MByte/sec, is pretty poor.OT: You thinking of updating the list post 5Mbit like you mentioned a while ago?

WiseguyNL Posted May 10, 2009 Author Report Share Posted May 10, 2009 I have the half open limit patched to 255. What value should net_max_halfopen be at in Utorrent? I have never gotten a 4226 error. My settings don't really differ that much from Switeck's recommended settings. I can't find anything on advanced settings in these forums. Are there any I should take a look at? Link to comment Share on other sites More sharing options...
jewelisheaven Posted May 10, 2009 Report Share Posted May 10, 2009 Change all Advanced settings back to defaults. What happens? Link to comment Share on other sites More sharing options...
WiseguyNL Posted May 10, 2009 Author Report Share Posted May 10, 2009 I still have the same problem. The only value I had changed was net_max_halfopen.I saw a message saying Disk Overload 100% in the bottom of the window(I was running Popcorn Audioconverter, though, so that could also be the cause). That can't be good, right? This seems to be a similar problem: http://forum.utorrent.com/viewtopic.php?id=56930 Unfortunately, he didn't post what he did to fix it. My drive is not running PIO.

Switeck Posted May 10, 2009 Report Share Posted May 10, 2009 Disk Overload 100% means your hard drive is unable to keep up with the rate of reads and writes being done. A defrag can help slightly for that...but mostly you need more or faster hard drives. Link to comment Share on other sites More sharing options...
WiseguyNL Posted May 11, 2009 Author Report Share Posted May 11, 2009 It seems to have fixed itself. I've been on a steady 1-8 mb/s(private tracker) all day now. I know it's not a disc problem and I haven't changed any settings, so I guess it was jsut my ISP. Link to comment Share on other sites More sharing options...
