briang5190 Posted January 8, 2007 Report Share Posted January 8, 2007 Hello,THe last couple of days the Internet has been really slow. I live in a 2-family, asked everyone if they were downloading porn or something big, everyone answered 'no'. Went into my roommates room, and he was using uTorrent, but it was finished downloading, and was uploading at 40-50k. I shut it down, Internet was fine. We have a 6mb/384k connection /w Comcast. But using the bandwidth tests (like SpeakEasy), it usually registers at least 9mb or higher, and ~350k or so upload. When my roommate's PC was using uTorrent, SpeakEasy would register less than a 1MB, and less than a 100k for the upload. Shut it down, and SpeakEasy said everything was fine. I've Googled the subject, and have followed many of the suggestions with the turning UPnP off, limit the upload rate, turning on protocol encryption, using port forwarding on the linksys. And between them all, they've helped. I limited his upload to 15k (still not downloading anything as torrent is finished downloading), but still SpeakEasy shows ~1.5mb down & ~200k up, which IS a significant improvement...but I guess I was looking for more. I mean I limited him to 15k, so doing the math from SpeakEasy's normal upload rate of 350k, I'm thinking it should be somewhere around 330k (give or take a bit). I'd even accept 300k, but almost half normal, not too mention the 1.5mb download which is roughly 15% of normal.Is there anything else I can do, or is this normal? I know it's an old router (ver 1 too), but using the latest official code (4/06). Should I try one of the unsupported firmwares?Thanks in advance.Brian Link to comment Share on other sites More sharing options...
Switeck Posted January 8, 2007 Report Share Posted January 8, 2007 15 KB/sec file transfer rate in µTorrent might take 150 kilobits/sec upload bandwidth and 30 kilobits/sec (or more!) download bandwidth. Link to comment Share on other sites More sharing options...
briang5190 Posted January 8, 2007 Author Report Share Posted January 8, 2007 RIGHT, I completely forgot/missed the difference between uTorrent's KB (kilobyte) opposed to ISP's bandwidth kb (kilobit). So that would explain the loss in upload bandwidth, since 15KB is roughly 120-150KB (so the 350kb is down to 200 or so makes sense). But why would the download suffer SO much?! I tested it again last night, and download showed a whopping 15mb (megabit, not byte). Yet with uTorrent on, and ONLY uploading (not downloading), it tests at ~1.5mb, which is only 10% of the previous 15mb test. Is the uploading relational to the downloading? So when you're uploading, you're taking away bandwidth from the downstream as well? Link to comment Share on other sites More sharing options...
Ultima Posted January 8, 2007 Report Share Posted January 8, 2007 It depends on your connection, but in most cases, the download doesn't share a chunk of the bandwidth with the upload. Link to comment Share on other sites More sharing options...
blzrd Posted January 8, 2007 Report Share Posted January 8, 2007 I am having the exact same problem. I am using comcast cable (averages around 2.5 Mb/s). When I have it uploading at around 40 my download registers at around 400Mb/s. That wouldn't be a problem except it also makes it have lag too. Let me explain that. When my browser sends a request, the return feed seems to be very delayed (10 seconds or more). I would like to know why that much upload could effect the system so much. My brother (the family admin) tells me that I won't be able to use bittorent anymore if it does that. Link to comment Share on other sites More sharing options...
blzrd Posted January 8, 2007 Report Share Posted January 8, 2007 Okay I don't know why, but when I changed my upload cap to 15k my bandwidth acted like I wasn't even uploading anything.My speakeasy stuff.Pre capD:6000 Kb/sU:400 Kb/sPost capD:5500 Kb/sU:128 Kb/sI can see where the upload measured out to be pretty close to what I would expect it to be, but now I am wondering why when I only have it at 15kB I only loos 500 of download. and when I have it at around 30 kB I loose 5000 of download.This is so confusing. I am just glad I found a happy medium so that I can still use utorrent. Link to comment Share on other sites More sharing options...
Switeck Posted January 9, 2007 Report Share Posted January 9, 2007 Such HUGE download speeds can only be sustained if your upload side can very quickly reply with "send more!" after every download packet. If you're even at 50% max upload rate, then your latency probably goes from ~20-50 ms to 200+ ms even to a next-door-neighbor ip. So responding quickly to get faster download speeds becomes impossible even long before you reach max upload speed.To get 5000 kilobits/sec worth of download speed (note I'm using kilobits/sec here!) probably takes 100+ kilobits/sec of upload bandwidth.
