WD EX4 always to high CPU

Hi my WD EX4 has the Bios 1.05.21. There is nearly 100% CPU . The Disk are always working… I have deleted all cloud users. If I want from my WD TV life see a movie, it has many Interrupts, because the WD NAS is to busy. What can I do to reduce the CPU? How can I see witch process needs the most cpu? Thanks for your answer!!! Novell1

Have you got a USB drive connected? If so remove it and reboot.


I solved the Problem. I disabled DLNA and rebootet. The CPU is much better, but I think this devices is limitted with CPU and Memory. I am not happy with the Performance (filecopy) my other NAS Zyxel and Synology are better.
