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.

About performance


As I stated in the opening statement of this book—performance matters. But what exactly is performance? What do we mean when we use this word? Sometimes we just want to say that the program runs so fast that the users don't detect any delays. We can say that the program is not lagging and that the user interface does not block. In other situations, performance means that a program finishes its execution quickly, or that a server can handle a large number of clients.

Knowing what we mean when we use the word will help us determine the best way to fix the problem. Whatever the approach will be, we still have to find out why the application is not performing as we expect. The original suspect should always be the algorithm, and to examine it we need to know more about how algorithms behave.

Algorithms are different in their nature. What we want to know about them when we are designing a program is how they behave when their input set gets larger and larger. Some run in constant...
