High CPU can slow down or even damage your NAS-device. This tutorial will showcase some possible sources of high CPU occuring!
If you are experiencing that your NAS is constantly running at a CPU level of above 90 percent, please follow these steps to deactivate two functions that might be responsible for this:
- Log in to the unit by entering its IP address and the credentials for an admin account (by default, username is “admin”, password is “1234”)
- Click on the myZyxel cloud icon located in the upper left corner of the screen and click on the switch of “Generating thumbnail for multimedia files, which is within share folders” to set it to “Disable”
- Close the Zyxel cloud windows and click on the “Control Panel” app on your apps overview
- Navigate to Service > Media Server, untick the checkbox “Enable Twonky Server” and click apply
Please note: You need to consider if you really want to deactivate these services. If you are fine with not using thumbnails in the gallery app and might want to use streaming stick as an alternative to the Twonky server, you can feel free to disable these.
