When analyzing profiling results, you may often want to perform some preparation, cleanup, and processing. For instance, if your code mostly spends time spinning around, you might want to filter that out. Before even starting the profiler, be sure to compile or download as many debug symbols as you can, both for your code, your dependencies, even the OS libraries, and kernel. Also, it's essential you disable frame pointer optimizations. On GCC and Clang, you can do so by passing the -fno-omit-frame-pointer flag. It won't affect performance much but will give you much more data about the execution of your code. When it comes to post-processing of the results, when using perf, it's usually a good idea to create flame graphs from the results. Brendan Gregg's tool from the Further reading section is great for that. Flame graphs are a simple and effective tool to see where the execution takes too much time, as the width...

Overview of this book
Software architecture refers to the high-level design of complex applications. It is evolving just like the languages we use, but there are architectural concepts and patterns that you can learn to write high-performance apps in a high-level language without sacrificing readability and maintainability.
If you're working with modern C++, this practical guide will help you put your knowledge to work and design distributed, large-scale apps. You'll start by getting up to speed with architectural concepts, including established patterns and rising trends, then move on to understanding what software architecture actually is and start exploring its components.
Next, you'll discover the design concepts involved in application architecture and the patterns in software development, before going on to learn how to build, package, integrate, and deploy your components. In the concluding chapters, you'll explore different architectural qualities, such as maintainability, reusability, testability, performance, scalability, and security. Finally, you will get an overview of distributed systems, such as service-oriented architecture, microservices, and cloud-native, and understand how to apply them in application development.
By the end of this book, you'll be able to build distributed services using modern C++ and associated tools to deliver solutions as per your clients' requirements.
