Overview of this book

Delphi is a cross-platform Integrated Development Environment (IDE) that supports rapid application development for Microsoft Windows, Apple Mac OS X, Google Android, iOS, and now Linux with RAD Studio 10.2. This book will be your guide to build efficient high performance applications with Delphi. The book begins by explaining how to find performance bottlenecks and apply the correct algorithm to fix them. It will teach you how to improve your algorithms before taking you through parallel programming. You’ll then explore various tools to build highly concurrent applications. After that, you’ll delve into improving the performance of your code and master cross-platform RTL improvements. Finally, we’ll go through memory management with Delphi and you’ll see how to leverage several external libraries to write better performing programs. By the end of the book, you’ll have the knowledge to create high performance applications with Delphi.

The helpful CPU window

In situations similar to the previous example, it doesn't hurt if you can look at the generated assembler code to check what is going on behind the scenes. Luckily, Delphi IDE provides a great way to do just that.

I will be the first to admit that examining assembler code is not for everyone. You can be a great Delphi programmer and still have no idea how to read assembler instructions.

If you found yourself in the previous words, don't worry. This section is included just for people who want to know everything. You can safely skip it knowing that you'll still be able to understand everything else in the book. However, if you're still interested then, by all means, read on!

The Delphi IDE gives us a few different tools for viewing the low-level state of the code and computer. They are stowed away in the not-so-obvious submenu View, Debug Windows, CPU Windows. The most useful view is called Entire CPU and encompasses all other views in that submenu. It is displayed as...
