The only purpose of multithreaded worker verticles is to register eventbus consumers and handle messages on worker threads concurrently without having to create as much instances as threads available in the worker pool.

So the answer to your question is: create a single instance, it will use all the worker threads available.

But if you plan something else, don't do it. For example, you can't create HTTP servers on a MT worker verticle.

More importantly, if you're starting a new application, avoid multithreaded worker verticles, they are deprecated and will be completely removed in Vert.x 4.
