Is this faster than without a 30s delay?
What do you mean by “speed up the whole workflow event”?
Scheduling a backend workflow is an action that happens as soon as the workflow is executed. It doesn’t matter the position of the action on the workflow (unless you refer to the result of a precious step), or the schedule date.
Scheduling now vs scheduling later can only have an effect on the workload of your app’s backend.

Usually you want to schedule it later because it has a meaning for your logic.
For example schedule a workflow that sends a reminder email 1 hour before an appointment.
