      I have the DN2820FYKH with 4GB ram and 120gb SSD.

      I installed Linux Mint 17 Mate and I have not only found that the keyboard and mouse are slow to react. I tried to find out why so I opened the systme monitor and I could see that the CPU usage is huge:


      -With System Monitor opened and just one terminal windopw opened I can see that CPU1 100% and CPU2 5%

      -With System Monitor opened and running apt-get update in one terminal window CPU1 100% and CPU2 70%

      -With System Monitor opened and running apt-get upgrade (installing upgrades) in one terminal window CPU1 90-100% and CPU2 100%


      Is it a problem of optimization (not good drivers for Linux Mint 17 Mate) or maybe my NUC is defective?


      Thank you in advance

          Hi titooo7,


          Let me help you with this.


          The information you have provided is interesting because as you say this is not normal; however, there are some troubleshooting steps to try:


          1. Test Windows versions.
          2. You can run the Intel® Processor Diagnostic Tool for Linux. Here you can download it:



          Intel® Processor Diagnostic Tool is software that will test the internal processor components and will generate a result.


          Maybe other users with Linux can share their experiences here.
