What is to much for a worklfow?

Hi friends, I’m using Google Translate because my English isn’t that good.

I’ve built this workflow that allows you to create and edit guest lists via Telegram and the web, as well as notify artists as soon as they arrive. It also includes a web form and an automatic contest, as well as a generator and resolution.

But I don’t know how many users the workflow can support before the load becomes too much.

How can I find out how much performance the system needs if it’s used by more than just 2-3 people?
