Task option: "Step not in workflow log"

[Rick Sample]

When this option is checked it only hides the "display" 
of the logged task from the standard view. 
All tasks are still logged in the Technical View. 
This is to not display background & misc steps that a  
user would not care to see if viewing his WF log. 
 
Question: 
Other than hiding the views of these misc tasks from the user, 
does hiding them improve performance or reduce any entries 
in any tables?
 
I don't believe they improve anything except not displaying in standard view. 
But anything that can possibly improve performance is worth the asking.
 
Thanks!
