Hey , first , just wanted to say that amule is good program , well done.

Now my problem :

I got 3 gb + shared files , lots of music and some big files ,
also I got a 312/156 connection , so my normal download speed is 32kb/s , and the upload speed is  15kb/s , people download from me in amule at 15kb/s , but the max download speed I can get is 4kb/s ( when I get a download ) .
that's wierd , I think I could get like 15kb/s download speed , since I upload in that speed , sounds fair to me since everything I download I'd be uploading for other people.

Maybe that's not even an amule problem , but any help would be welcome.

it's a network problem. first days you get slow download rates, then you go gaining credits and go gaining speed in downloads.
read http://www.amule.org/wiki/index.php/AMule_is_slow of more info on this

I got the same problem. I have a high ID, and my credits file knows about 14000 odd clients, yet the upload-download ratio is consistently between 20-1 and 40-1.

I can't leave amule on for more than 1 day at a time, so *perhaps* that is the problem but...

I noticed that a few seconds after I connect I'll start downloading a file. That will last for another few seconds, and then I'm cut off.

People are uploading off my machine at a steady 24 k per second, and I get no download. This has been going on for about a month!

ye that's a problem since you can't stay in clients queue for more than a day. not a big problem, but makes you loose quite big chances, since the more you stay in a client's queue, the more credits rate you win there.

> That will last for another few seconds, and then I'm cut off.
that's some f***ing *donkey clients that snd you few KBs and cut the connection. this way they get more credits. and of course, they spoil the network. they are banned as soon as they are known, but... some are still out there as you can see :-(

you must be downloading pretty rare files then. the speed isn't aMule's fault. the network has a specificaction and _all_ clients must follow it. otherwise, the client is banned. of course you can modify the client to get some better performance, but that will spoil the ed2k network and we are absolutely against those practices.

Well, to me this sound like a network misconfiguration problem. Once I myself had one, until I understood what to do. I have a 42kB/8kB connection, and I could download at a constant 42kB/s UNTIL upload reached 8kB/s. Then suddenly my download speed dropped to almost zero ~3kB/s.

Reason (this all is TCP level and has nothing to do with aMule itself): To download, for each packet you receive you send an ACK packet back to the sender, to let him know you got the packet. If your upload bandwidth is fully used by "upload packets", this TCP overhead will ahve a hard time until being sent - waiting long in queues, maybe timeouting, which can even cause the connection to be dropped, etc - and this causes the download stream to slow down.

Solution 1 (in aMule): try to lower your max upload setting, first about to half of the line capacity, then later raising it slowly, checking where it starts to suppress downloads.

Solution 2: use some traffic shaping software, that assigns priority to ACK packets so they don't get disturbed by any amount of other traffic.

Hope that I could help.

which programs do this?

In linux use "tc" command. You should read documentation first.

wondershaper, dsl_qos_queue, just to mention two examples. Try to search the internet for 'bandwidth limiter' and 'traffic shaper'. With the good keyword it gives you tons of these programs.
