You have to do so many things just to use more than a single CPU core. There are other language platforms and runtimes where using up the entire available CPU cores is the default option, and taking advantage of multiple cores within the app is easy by design. I can see why people like pm2, similarly to why I can see why people like Nodejs. But I think pm2 is half-baked, and Nodejs's greatest design feature (single-threaded async execution) is flawed by design.
