That's up to 50 MIPS! What's it doing? Only standard indicators used, and most Unity lenses and scopes not installed. Internet access is available and unfiltered. Standard Intel Mobile 4 GPU. When I set the datetime indicator to show seconds, unity-panel-service uses an additional 1% of CPU. That's 10 million instructions each time the clock ticks!
