title: How vert.x is single threaded?
body: <p>From my understanding, each vert.x instance will be assigned an event loop. Event loop handles all the request an other task for that particular instance. Event loop is a thread, I think. When there are multiple vert.x instance deployed, each instance have there own event loops right? That means there are multiple thread(multi-threading) exists. This is how I understood. This single-threading concept causing me so much headache. Any help will be appreciated.</p>
