PROBABLY means that this application is okay under any reasonable loads.

Check the constraint tests results to see what kind of loads might be a problem.

YES means that this application is okay under any load.

NO means that this application is not reasonable. See the Constraint Tests results to see what resource you are short of. See if you can increase this resource, or decrease the number of port networks.
