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 chapter provided a broad overview of the topics we'll be dealing with in this book. We took a look at the very definition of performance. Next we spent some time describing the Big O notation for describing time and space complexity and we used it in a simple example.

 In the second part of the chapter, we looked into the topic of profiling. We used a manual approach and specialized tools—profilers—to find the slowest part of a simple program.

In the next chapter, I'll briefly return to the topic of selecting the correct algorithm for the job. With a few examples, I'll show you how an algorithm can make or break a program's performance.
