Summary

0001209: amule doesn't use all the brandwidth

Description

I'm using amule CVS 20071125 on a server with a 100Mbps connexion to the internet. amule and amulecmd don't use the whole upload brandwidth, even if I set max UL rate to 0 or 12000kBps. It uploads data at a 1~2MB/s rate and queue clients even if there is still free brandwidth.

Additional Information

At that rate amule is consuming about 30% of cpu so CPU is not limitating. Still at that rate the ping time is good, so I don't think that amule "detects" that the line is full..

This is exactly what I am having. So I guess the problem must be here. Am I wrong? modifié le : 11-29-07 11:17
