Note: as @clibois mentioned below, due to the DRM Netflix uses, all decoding has to be done in CPU, making it somewhat choppy.

Note 2: Even the RPi 3 suffers from these CPU limitations. There is the potentially risky option of overclocking your RPi 3, but I haven't tried this.

If you manage to get smooth playback, please contact me, or post your solution here

UPDATE: I can no longer get this method to work. I have tried using Chromium v47, and v48, and both result in Netflix error "Oops, something went wrong" / C7053-1807, for which I can find no description online. If you manage to get things up and running, please contact me!

Node.js异步处理CPU密集型任务

Node.js擅长数据密集型实时（data-intensive real-time）交互的应用场景。然而数据密集型实时应用程序并不是只有I/O密集型任务，当碰到CPU密集型任务时，比如要对数据加解密（node.bcrypt.js），数据压缩和解压（node-tar），或者要根据用户的身份对图片做些个性化处理，在这些场景下，主线程致力于做复杂的CPU计算，I/O请求队列中的任务就被阻塞。

Node.js主线程的event loop在处理所有的任务/事件时，都是沿着事件队列顺序执行的，所以在其中任何一个任务/事件本身没有完成之前，其它的回调、监听器、超时、nextTick()的函数都得不到运行的机会，因为被阻塞的event loop根本没机会处理它们，此时程序最好的情况是变慢，最糟的情况是停滞不动，像死掉一样。

一个可行的解决方案是新开进程，通过IPC通信，将CPU密集型任务交给子进程，子进程计算完毕后，再通过ipc消息通知主进程，并将结果返回给主进程。

和创建线程相比，开辟新进程的系统资源占用率大，进程间通信效率也不高。如果能不开新进程而是新开线程，将CPU耗时任务交给一个工作线程去做，然后主线程立即返回，处理其他的I/O请求，等到工作线程计算完毕后，通知主线程并将结果返回给主线程。那么在同时面对I/O密集型和CPU密集型服务的场景下，Node的主线程也会变得轻松，并能时刻保持高响应度。
