too slow downloading
« on: July 30, 2006, 11:44:42 AM »
Hi to all!

I have a problem, I use amule 2.1.3 on mac OSX MacBook.

The all download speeds are under 3.0kB/s.. I don't know why. Is it need for some special settings?

Thank you

Regards

Do you mean your total download speed does not go much higher than 3k/s? If that's the case, see http://www.amule.org/wiki/index.php/AMule_is_slow.


If you mean that your download speeds per single source don't go much beyond 3k/s then I think I can confirm that.
I got a chat message just a few days ago from someone who said that he was trying to push my download from him (via friend slot) but that he was never able to upload to me much faster than at 3k/s, even though he routinely manages to give other people uploads of 80k/s.
I started a little investigation then and it turned out that I seem to be never downloading from a single source at a speed faster than 3.6k/s. I had not noticed this before because I often have download speeds per file of 15k/s or so and my overall download speed is usually pretty decent too when I download popular files with many sources. But now it turns out that is because I download from a whole bunch of people at once.

I wonder if this could be happening because of my slowing down the core_timer in order to combat aMule's resource hunger. I'll run a quick test to find out.

Alright, I did a little more testing and it really seems like tempering with the core_timer negatively impacted download speeds. Given that increasing the core_timer interval only reduced aMule's cpu hungriness marginally, I will go back to using the original value (100 ms instead of 500ms) and we will have to find a more substantial solution to aMule's cpu hogging behavior.

I recently installed aMule 2.1.3 and seem to be experiencing the same problem, although in my case the total download spped for each file never exceeds 3.9. I am a former user of eDonkey, with which I was getting much faster speeds per file. With aMule I rarely get much above 25 total, despite capacity of some 60-70.

As I said, I found the cause of the slow connections (the prolonged core_timer interval) and fixed it. With that change in place, I can again download from a single source at 40k or so. I will post a new CVS version with that fix later tonight.

Thanks for that. I am nervous about running the update as I am not a techie. But assume it will be incorporated into a stable version for the Gui quite soon!

I have now run the update but it crashes every time I click on the Files Transfer icon!

Thanks for letting me know, mexicanray. I just realized that I had used an unmodified wxWidgets install on my Tiger system for building aMule. In order for wx to run properly with aMule on OS X, wx needs to be modified to use OS X's built-in vswprintf function. I will post an updated Universal Binary binary shortly.

Thnx. I can confirm though that my average overall download speed has doubled, so assume that is due to a speed-up from each source!

Ok, the fixed version is available now. Sorry for the inconveniences that this has caused. I have two systems with about 4 wx installs on each one, and even though I am usually pretty careful to not mix things up, this time something must have gone wrong.  I thought I had made the necessary changes to my tiger release wx install, but apparently I had not. So sorry again, things should be ironed out now.
