+## idlejitter.plugin
+
+It works like this:
+
+A thread is spawn that requests to sleep for 20000 microseconds (20ms).
+When the system wakes it up, it measures how many microseconds have passed.
+The difference between the requested and the actual duration of the sleep, is the idle jitter.
+This is done at most 50 times per second, to ensure we have a good average. 
+
+This number is useful:
+ 
+ 1. in real-time environments, when the CPU jitter can affect the quality of the service (like VoIP media gateways).
+ 2. in cloud infrastructure, at can pause the VM or container for a small duration to perform operations at the host.
