bad performance
« on: December 17, 2004, 10:55:33 AM »

hi there,

my mac amule from the homepage worked fine for about 3 weeks (upload, download 20 to 20 +-), but in the last few days performance is terrible.
Yes i have a high id and all the other normal checks are also fine.

I changed nothing in the configuration. My upload is ok but my download speed is terrible (1 kb). It seems i have a lowId but the id is high. It looks like the amule looses connection. When another client wants to upload data, most of the time the 0.0 kb appears in the download tab and then it disapears without uploading any data. The best i can expect is downloading from a source for about 20 seconds with an amount of 20 to 80 kb.

it is very annoying because last week it worked very very good and i have changed nothing. :(

i dont know what i can do, i tryed everything. Has anyone else this problems in the last 3 days or am i the only one ??? is there a new serversoftware or a new EMule client that dont want to speak to us amules ???

thanks robda  :(

"The best i can expect is downloading from a source for about 20 seconds with an amount of 20 to 80 kb." <- :( nothing can be done about that. some clients suddenly disconnect, you know

"in the last few days performance is terrible." <- try restarting aMule (close + open)

some clients would be ok but all of them not. i restarted amule 100 times with no effect. As i said before i got those problems since 3 days without having changed anything.

i now try the new prerelease and i hope it works better. thank you

i hope too ;)

anyway, it's just bad luck what you were having.
as you see, once you restart aMule, it's memory has been deleted so everything starts from zero again. So, it will work as good (or as bad) as it did 3, 10, 1000 days before. The only way to alter it's conduct would be to modify the amule binnary, and aMule doesn't do so ;)

Please test current pre-release and check

i am experiencing the same connection issues here that you describe, robda: sometimes downloads begin at 0.0k/s and stay there for some time until the connection is closed. other times, a download starts at say 4.0k/s and then gradually decreases until after a minute or two the connection is closed.
i just migrated my main donkey to amule -- before i was running amule only for testing with only a few smaller files queued for download -- so i'm not sure if this behavior was present in older versions as well.

it seems really odd that your client would not exhibit this behavior for weeks and then suddenly start -- are you sure you didn't replace it with a cvs build or change anything in the preferences? are you maybe now sharing a inet connection and you weren't before?
i think it's extremely unlikely that a change in the server software could be responsible for these issues because the problem obviously concers the client<-->client communication.
on the other hand it also does not look like it's related to the version of the other client: i seem to have the issue regardless of whether i download from an emule 0.30 or 0.44d...

i think some more low level testing is needed here.. :)

hi lionel77,

no performance improvement for me so far. It is very very frustating. I have tested the new build with no improvement. I have deleted the .amule folder except the credit file with no improvement and now even deleted the creditfile. :( (of course backuped it ;) )
i used edonkey emule and now amule for about 4 years and i never had such crazy performance.

no client gives me more than 50 to 250 kb. It is normal that some clients (10 - 20 %) only give this little but not all clients. It seems like loosing connection, a timeout or something like that. I dont kown.

and you any improvements ???

Hi robda, maybe your ISP changed policy? Did you (can you) try amule under linux / amule/emule under windows to compare the behaviour? If they act crazy too, it has to be something with your ISP :-(

@ sssnake
i will try the idea to test the performance with my old win emule client. When a ISP changes the policy the only thing they can do is blocking ports and that would result in a low ID !? Or can they do more than than blocking ports ????


thanks robda

i tryed my windows emule client and it works very good, so the ISP and router cant be the problem.
i think the mac or amule must be the problem. I will test RC8 on my powerbook and see what happens.

yes, your isp is not the problem -- i am experiencing the exact same issues here with two different machines/inet-connections.
my guess is, it's either an issue of the mac wx version or a remaining byte-order issue in the amule code.
we need to do more testing and then determine the exact reason for the lost download connections...

hi lionel77,
i have tested the new rc8 build on my g4 power book 1,33 gHz and it works very very fine. It uses the same router configuration and the same amule preferences as my previously used mac.
The previously used mac with the bad performance is a g3 iMac with 350 mhz and 512 MB ram. Could low cpu power be the problem ?????

what machines do you use ????

what changed between the new RC8 and the last RC8 Mac Prelease ???? because i have not tested the new rc8 release  on my iMac 350 mHz.
When i look in the info of the new rc8 application it says that the creation and modification time is the
8 of december. hmm strange.

bye and happy testing

now i got the same problems on my power book and of course i did not changed a single thing. Yesterday i have installed the new amule and for 24 hours it workes very good.
after 24 hours my os told me to free up some memory because of no free disc space ( another memory leak ?? ). The problem was that amule was the only running app so i could not free up some memory.

i had to restart my mac and amule. And after that the same problems as described some posts before. Am i and lionell77 the only ones with this problems.
is there a amule developer that mainly uses amule on mac os x ???

bye robda  ;(

Hey, I'm the man on the Mac development. Problem is I have to use vnc & ssh to develop on Mac.


But I of course want to help you fix it. lionel77 and ken might want also ;) They can be considered as developers... with a Mac.
