bandwith

[tyrellcorp]

hi there,

i have been useing bitcomet for some time now and i have been through all of the port forwarding issuses and firewall problems, but there now seems to be another problem... when i start to download a torrent theres this 30 second delay and the green arrow is there and i am downloading but its just in bytes , then suddenly woosh i am downloading one torrent at about 70k/bs , great! , but then it will drop down to 25k/bs and stay there. Then if i start another torrent it will eat into the other torrents speed , so that 25k/bs becomes shared between TWO torrents. Whats causing this? do i have a bottleneck somewhere ?

It seems a little crazy to have so slow download speeds after i look at all of the remote and local connections i have with all of those peers uploading . would it be a server problem or inside my lan card?

any help on this would be most grateful..

This may be related to your upload speed setting. Most home broadband connections are asymmetrical, with downstream speed a lot faster than upstream. But the upstream part is important. Not only are you sharing pieces outbound, but every piece you recieve must be acknowledged or it's assumed the packet was lost, and needs to be re-sent. Then there's other internet use. So it's quite possible for all that traffic to jam your upstream connection.

You need to limit your global maximum upload speed in BitComet, to about 80% of your actual, measured upstream rate. Don't guess and don't assume it's the same as your download speed -- it isn't. Find a web site that will tell you your actual speed both up and down. Pick a site that's reasonably nearby: if you live in London, don't choose one based in Taiwan or San Francisco. Shut down everything else that might use bandwidth before you do your test. Do a screen copy of the results. Do a screen copy. Do a screen copy.

Now convert, taking due care with unit conversions, the actual upstream rate to BitComet's standard of KB/s, and set your global maximum upload speed to 80% of that. This will keep BitComet's uploads from drowning out the acknowledgements, and give you enough headroom to perform other tasks at the same time.

many thanks for your reply.But i am fully aware of the up load limits and how to set them. All i am concerned about is that when i run bitcomet it doesnt seem to use all of my available bandwith where as IE is fine when i download stuff from the internet,even if i have either 1 torrent or 5 the amount of speed i get is always half my usual speed, which is incidently 123kb/s download and 24kb/s upload. i have been download for a long time now with the upload set at 18kb/s and in the past this has given me about 115 kb/s download. at this time i never seem to get any more than 54 kb/s. i have been through the forums and re set the other settings as per advisement , also to the point of uninstalling everything and starting with the default settings within bitcomet ( wish there was a re set to default button within bitcomet?!!)

i have been reading about other people "sharing" your bandwith so they get faster downloads is this possible and how do i find out if some stanger is doing this?

two years ago when i first started useing bitcomet ( with all the default settings) i never had any of theses problems you just clicked and you download simple..

That sounds suspiciously like bandwidth throttling. Check google for reports of your ISP doing this. In the meantime, in your Advanced/Connection settings, enable encryption and see if that doesn't pick your speed back up.

I'm glad to see that I am not the only one with this issue. Is there a Restore Defaults in BitComet or do I have to completely reinstall the program? Any advice would be appreciated. :)
