What happens when you activate an application from Alfred

[nikivi]

I have a performance issue when I activate an app from a Keyboard Maestro from following macro:

 

This issue disappears if I open the app from Alfred like this:

 

 

 

I thought that it activated open -a 2Do under the hood but running that command still gives me bad performance as the above KM macro. 

 

I would like to know what Alfred actually does to open / switch focus to the app when triggered through the Alfred prompt.

 

Thank you.
