I'm aware of the 2 methods of running the automation so that you can run it more frequently (less than 1 hour)

* Adding wait periods between SQL activities within 1 automation
* Cloning the automation and scheduling it to run at the hour/halfhour/etc.

Which method of the 2 has less downsides to the platform performance?

Is using SSJS method better than the 2 above?
Thanks!
