powertop shows high Serviio events per second

Using Powertop v2.5 on Ubuntu 14.04.1, on the overview tab, I see Serviio v1.4.1 top of the list for events per second:

  Code:

     Usage       Events/s    Category       Description
10.2 ms/s      45.3        Process        java -Xmx512M -Xms20M -XX:+UseParNewGC -XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=20 -Dffmpeg.location=/shared_data/serviio


I have set "Pause between refreshes" to 360 minutes, and have "Keep library automatically updated" enabled.
