Outline · [ Standard ] · Linear+ Too high upload speed

Hi,
I know this might be a problem that hasn't anything to do with the eMule+ Mod but maybe you could help.

I've limited my upload speed to 10kb/s (I've got TDSL) but it seems that the upload goes up to 16kb/s.
eMule+ tells me, that people are only downloading with the 10kb limit but every external program tells me that I've reached my upstream limit of 16kb/s.
The problem is that the download slow when you reach that limit.
So, when eMule is running my download go down from (max) 90kb/s to about 2-5kb/s and eMule itself only downloads with 5-10kb/s.

Well I don't know what happened because everything used to work fine and I don't think that I have installed any new software or changed any settings (I've already reinstalled eMule twice, didnt work).

Maybe it has something to do with my Norton Firewall, but I'm pretty sure that it's configured right.

Well, in a nut shell my question is how and why does eMule apparently upload more than 10kb/s ?

Yes, if you flooded (using up to the limits) your Upload link, then downloads become very slow ...

You forgot to count Overhead : eMule UL + eMule Overhead = Total eMule Traffic.

Make sure that you have Lancast DISABLED.

First, thanks for the fast reply.

I've got lancast deactivated.
There's no way to deactivate the overhead ?
And usually it 10kb/s + Overhead should work fine I guess, because that's the standard setting ?

Overhead depends on how many concurrent downloads you have, how popular they are, max. sources per file, queue size (not really, but ...), number or shared files etc ...

If you have enabled "leave queue if QR>xxx" (Preferencess-->>Connection) enabled, then disable (uncheck) it -- 'cos it generates a lot of useles overhead sometimes ...

Anyway, it'll be a good idea to provide us with your eMule's and system's settings. Reading FAQ is also appreciated ...


* Make sure that you don't have any MSBlast or MyDoom installed

* Use TMeter or NetLimiter (for example) to find out wich programs are using your traffic.

* Do you have any other P2P client nad/or FTP/Web server running ? ...

The only really efficient way to reduce overhead is reducing the overall number of sources (around 3000 is what I´d consider an upper limit for a TDSL line)

So you have 2 choices:

1) reduce the number of active downloads by pausing/stopping some of them

2) reduce the number of sources per file (which is what I would do)

Most people think that more is always better, but in this case it´s not

Is there a way to find out if I really have such a huge overhead ?
My max. connections are only 500 (20).

I surely dont have a virus and the problem with the high upstream starts when I'm running eMule.
I have no FTP Client, P2P or webserver running. Nothing, except ICQ.

I'm using Win2k latest SP on a P4 2,5ghz, 512mb ram.

Oh and btw: I often get a lowId. Then i restart eMule once or twice and everything works fine again.

Sorry for double-posting but I found some more disturbing information.

I've tried the eMule Connection test page.
eMule and NIS is running and I get this error on my port 1234:
timeout
this means, that we even did not receive a
RESET signal; maybe due to a 'stealth' firewall

When I'm deactivating the firewall i get this error on every port:
error/resest on ip xxx.xxx.xxx



There seems to be something terribly wrong with my system.
Couldn't have something to do with the newest IE6 release ?

If you really want to continue using NIS, you have to open the ports for emule.

WRT sources/connections: I didn´t ask you to reduce max.connections limit, but max.sources per file limit.
That´s something completely different

As I already mentioned above : uncheck "Leave remote queue if QR>3000" -- this option may generate such extra overhead...

I'm too stupid.
I only checke max sources per file in the advance dialoge (load/save) not the file dialog.
Cut it down from 400 to 100 and external downloads are fine again.
We'll see if eMule gains more speed, too.

Thanks for your help.

What did you use to measure the upload limit on your ISP? Or did you just make an educated guess at avoiding flooding?

Can someone recommend a good tool for this? Thanks.

What exactly do you mean? The maximum upload rate should be clearly advertised. If not, go to a speed test site like www.dslreports.com and do a test. Your upload speed is most likely going to be a multiple of 128Kb/s so that should give you some idea.

The total upload cap before your ISP will cut you off is harder to find. Most ISPs don't want to admit they have one. They advertise unlimited Internet and they're not really providing it. Comcast has a limit around 60G a month. If you go over that repeatedly you get your connection terminated.

If that's what you're talking about, there are forums for many ISPs, not necessarily on the ISPs home site. Do a search. You should be able find out there.

Thx. I'll try dslreports. I actually forgot about that site.

To answer your question and help clarify, I was asking about the actual upload capacity, not an advertised capacity, and not some number arbitrarily chosen by the ISP before they shut me down.

Thanks for the help.
