Hello! it happens to me that when the application is minimized the download speed of files goes down a lot. It happens to me with aMuleCore 2.2.6-x86 in Mac OS X El Capitan 10.11.6 (15G22010).
If I update the aMule to a new version it closes this is the only version I've found that works well but when I put a window of any other program on it or minimize it as the comrade says its speed drops to minimum ... I understand that the operating system gives you fewer resources ... any solution? Thank you so much!
