> 1- making the workflow fire on change.
The workflow is not running until the event occurs. So no running workflow or overhead until the event.
> 2- dragging a onworrkflowchanged activity which is fired when the item is change
The workflow would like already running when it hits this activity, at which point it will "go to sleep" and wait for the change to occur. This would be used in a workflow that would be started manually, or when the item is created, or any other event, and
then run to this activity and then pause and wait.
