public abstract class EverSlowingAbstractAjaxTimerBehavior
extends org.apache.wicket.ajax.AbstractAjaxTimerBehavior

The component will get updated, but ever less often.

This means that initially the refresh rate is once a second, so the user will see the data updated quickly. But after a while, it will gradually slow, until it reaches once a minute.

This is a good balance between the user seeing the data update frequently (at the beginning), and not spamming our server if lots of people leave their web browsers open.
