since I'm using Amule > 2.13 I experienced problems with the CPU load. It started at about 15% and increased slowly to 100%.
I think I finally found the reason for that.
As long as I have "Try to upload full chunks" disabled, this problem occurs. But as soon as I enable full chunk upload, CPU load instantly goes back to normal values. Seems like that there is a problem calculating the amount of data that is supposed to be uploaded.
