Delphi High Performance

By: Primož Gabrijelčič

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.

This was the final chapter, dedicated to multithreading, which put a finishing touch on a story line that started in Chapter 5, Getting Started with the Parallel World. I started by describing all the bad things that can happen when writing parallel code, then spent one chapter showing the cumbersome TThread, which makes multithreaded code such an unnecessary pain, and then in this chapter I finally moved on to the nice parts of the puzzle—tasks and patterns.

The chapter opened with a discussion of tasks and patterns—what they are and how they can be used to simplify multithreaded programming. For a bonus, I threw in a short treatise about variable capturing, which focused only on one problematic part—the capturing of a loop variable.

Then we looked at how we can use tasks to split a loop into multiple parallel loops. We saw that there's quite some work involved, particularly around task creation and setup. On the way, we also learned about the thread-pooling concept.

The last part...
