Introduction

Big open source projects are huge, such as the Servo browser in Rust. I have counted the lines of code for you. There are almost a hundred thousand lines of code in the Servo project. To develop such a big project, knowing how to debug in a right way is very important, since you would like to find the bottleneck in a fast and efficient way.

In this article, I will teach you some tips to use GDB developing and debugging your Rust code and the Servo project. The debug method can be also applied to C/C++ as well.

Introduction

With a profiler, we can learn more about how software runs—such as memory usage, CPU cycles, cache misses, I/O time, and more. This information is extremely helpful for locating performance bottlenecks. The ultimate goal of performance analysis is to find what slows the program down and maximize performance.

This post introduces perf on Linux. Using a simple program example, I will demonstrate how to analyze a program with perf, and you will see that using a profiling tool can make it much easier to identify the root cause. This post references Gabriel Krisman Bertaz’s Performance analysis in Linux。
