How many users can an interactive DataTable handle?

I’m in the final stages of deploying my application that I’ve developed for my team. The end purpose of this application is to allow supervisors to make editable changes to a data-table whenever one of their associates didn’t have any recorded transactions in a given hour. That particular hour would be tagged as an Indirect Labor Hour, or an hour wasted depending on what productive thing the associate did.

The app is going to be deployed on multiple locations and I was wondering how the datatable is going to handle multiple requests at once when the changes made to the datatable is going to be pushed to a postGresQL table i’ve set up.
