Everyday, various Facebook mobile apps are being used by over one billion devices around the world. In this talk, I will share with you how Facebook thinks about about mobile performance.

We'll look at some of the challenges we face and how they become an engineering problem at scale. We will explain how we tackle them by treating performance as a first-class feature.

Then we'll take a high-level look at some of our performance tools, and then do a deep-dive into tools for regression prevention.

每天在世界各地，超过10亿的手机在运行着 Facebook 的多个移动应用。这个演讲将和您分享 Facebook 对移动应用性能这个工程问题的理念。

我们将解释我们所遇到的一些挑战，向您展示移动应用性能是如何成为一个大型的工程问题的，以及我们如何将性能第一深入到工程的各个环节。

之后我们会介绍一些性能工具，并着重深入介绍性能退化检测的工具。
