Each ImageJ command, plugin or macro runs on a separate thread. So  
try starting a second task, operating on a different image, and see  
if both CPUs are used. Also, processing and image display run on  
separate threads, so try running a task that continuously displays  
images and monitor the CPU usage. Such tasks include live video  
capture, stack animation, the built in benchmark  
(Plugins>Utilities>Benchmark), or any of Kai Barthel's plugins (3D  
Color Inspector, 3D Surface Plot, Volume Viewer).
