    Default Download / Upload

    When we use torrents we upload the file at the same time. My connection is 32 KBps and if I set upload and download as unlimited, will it upload and download at 32 KBps at the same time. Is uploading independent of download. For eg. Can we download at 32 KBps and upload at 10 KBps.

    Yes both are independent, you can regulate any speed you want (within your bandwidth). Yes you can download at 32 KBPS and upload at 10 KBPS.

    Yes you can set the download speed to unlimited and set the upload speed to 10KBps.
    But in ip 117 there is no problem with upload and download at the same time.
    if you ADSL Modem's GUI shows to you the download speed more then 2048KBps and upload speed more then 256Kbps then you can set the download and upload speed to Unlimited. This will not effect your downlod speed.

    In Kolkata at the ip 117 with The plan of UL750 the upload speed is maximum 62KBps and downlod speed 32KBps at the same time, where the ADSL Modem's GUI shows the Download speed 10,000 KBps and the Upload speed 863KBps.

    It's depend, if the torrent have good seeder then the leecher, for example if a torrent have 50 seeder and leecher is 10 to 20 then there is no problem if you set the uplod speed at low KBps.

    no, It wont be affected, not at all.
    They are like two different lanes of traffic, no mater how speed the first lane go, you can always regulate the second lane.

    Uploading and Downloading speeds cannot be the same in ADSL ( ASYNCHRONOUS DSL )...The upload speeds are usually half or less than the download speeds. I dont think the upload speeds have any effect on Download speed.

    But do not set your upload limit to very low value, this would affect your download as torrent works in give something and get something methodology.

    So if everyone in the tracker started limiting upload, then download speed will definitely get low.

    1. Upload speeds are independent

    2. Upload speeds are half or lesser than half of download speeds

    3. Capping the upload speeds will automatically result in decrease in the download speeds ....... This is because of the way torrent functions

    What I am trying to learn is, will my data transfer per hour will be download + upload. ie, I can download 100 MB per hour as my connection is 256 Kbps. Will total bandwidth consumption will be more 100 MB + 50 MB = 150 MB.

    This happens only when you have more than 1mBps line. here we are having just 32 to 256 kBps line so it wont matter much.

    Yes thats correct. Your data transfer will be download + upload only, but by restricting the upload speed you can not increase the download speed.
    Ex: 32kBps for downloading & 32kBps for uploading. Now you can restrict the upload to 10 kBps but the download speed will not become 32 + 22 = 54 kBps it will be 32kBps only.

    These are like traffic lanes with dividers if your lane is full and the coming lane is have you cant go on the other side, you have to manage in your lane only.

    Excellent presentation. Need to spread some love

    Some it is not unusual to have more than 256 X 60 X 60 Kb in one hour. The value will be 112.5 MB + Upload. Taking upload to be half, for 256 Kbps the maximum download per hour is 168.75 MB.

    Its worth noting that Max Upload speed will never equal that of maximum download speed

    Always max upload speed is lesser than max download speed

    I dont quite agree with everyone here. Torrent Upload & Download speeds are not totally independent. There are many factors:

    1) First of all, the speed of a torrent depends on its status(number of seeders and leechers). More the number of seeders than leechers - more the speed (download).

    2) Private trackers are fast compared to public trackers in mst cases.

    3) If a torrent has almost equal number of seeders and leechers or if the number of leechers is more than seeders - the upload rate can affect the download rate.

    4) If the upload speed is kept very low (2-3 KBps), the download speed also decreases if the status of the torrent is not very good(something like 100 seeders and 1 leechers).

    The reason for this is many users ban(temporary ban using the torrent client) peers who dont upload at good rate.

    5) If the Upload speed is very high - it also affects(decreases) the download speed slightly.

    Follow these two thumbrules:

    1) Always keep the port number of your torrent client above 52,000.

    2) Keep the Upload rate about 2/3 of your download speed limit. For ex:- If the download speed of your connection is 32 KBps, Limit the Upload speed around about 20 KBps in the torrent client. (Specially for cases 3-5 above)

    I dont remember the source of these thumbrules. But, these are recommended in many torrent speed boosting guides.

    I once discussed this topic in details on the forum in my early days. Couldnt find that now.

    Not necessarily. If I dont limit my upload speed, Upload speed goes beyond download speed many times. (specially on torrents with many leechers).

    Absolutely correct. No matter what you do, the download/upload speeds wont cross the ISP limit. (unless you are very lucky)

    I dont know the exact reason. But, i read it a few years back in some torrent speed boosting article. Also, saw the same in a video tutorial for torrent speed boosting. most such articles suggest keeping higher port numbers. some sources suggest ports above 30,000/40,000. But, I always keep port number above 52000 and this gives good results(not very noticable though).

    D/Ling from private trackers is a sure shot way of maximizing your available bandwidth.

    @ saurav,

    Download/Upload are independent of each other. Don't think about Torrents alone. If you set your upload to a low limit using bandwidth limit tools say Traffic Shaper, your download is not going to get affected in anyway.

    But in case of torrents, only the clients ban the low upload speed torrent sources and not because of any dependency.

    Rep for your work
    Same thread was discussed with me here Download / Upload - SKAPadmin.net Forum - Security Forum. Have a look.

    Just for safer side that we are not using any reserved ports. Most of ports above 32000 are free and not used by any other protocols.
