Xiaoming,
The easiest way I found is to put a very low limit like Andrea suggested
and flood GeoServer with many parallel requests, while maintaining the
default memory settings (so, low heap). If it's not working you will crash
GS pretty quickly. If it's set up correctly, you will see GS throttle the
requests. VisualVM is helpful here to track memory consumption, it will
grow very fast if control flow is not kicking in.
