Query Cost Normalizing

Tibor Karaszi does the math:

There are plenty of articles out there recommending you to up the “cost threshold for parallelism” configuration option. Most of you already know this, if not fire up your favorite search engine and spend a few minutes reading about it.

My aim here is to do a totally non-scientific test if I can translate these fictitious seconds to what they correspond to on a reasonably modern hardware – which is my laptop from 2020.

This is one interesting approach to back into a cost threshold for parallelism.
