Vertx http server only creating one instance

I am creating a simple micro service using vertx and when i start my server it only create one event thread when available is 12.

My code to start server is 

public static void main(String[] args) {
    Vertx vertx = Vertx.vertx();
    int processorCounts = Runtime.getRuntime().availableProcessors();
    DeploymentOptions options = new DeploymentOptions().setInstances(processorCounts);
    vertx.deployVerticle( HttpRouter.class.getName(),options);
}

And my http router looks like this

@Override
public void start() throws Exception {
    super.start();
    Router router = Router.router(vertx);
    router.get("/").handler(event -> {
        event.response().end("Hello World");
    });
    vertx.createHttpServer().requestHandler(router::accept).listen(8001);
}

What is your process for testing? I assume you opened a browser and hit refresh on the same page. Then yes, the same verticle instance will handle the requests. The reason is Vert.x load balances connections among verticles instances, not requests.

Open a different browser and you should see different event loop names.
