How performant will JS automation be? Can we expect to be able to loop 1000 tasks in 400ms?

For example, would it be reasonable to loop through 1000 active tasks in under 400ms ( which is pretty attainable on V8)

I’m pre-designing my workflow with automation in mind, and I’m curious if it’ll be possible to run a script on the database everytime I save a change without noticeable hitch.
