Question

In nodejs if you do something as follows const before =

Date.now()
async someDBIO()
const after = Date.now()-before

Ideally the after time would give you the time it spent in DB and if you do same thing when the request is received and the request is completed you get the same time, if I am not wrong.

The question is, if simultaneously somewhere else in code if I am doing CPU intensive task, then in a large number of RPS where a lot of such calls are sent to DB
because the main thread is not free enough to go back to get the get the callback data

The after time would be more than the actual time it took to do the DB operation, wouldn't it?
