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.

Chapter 8. Using External Libraries

We've seen many different ways of improving program speed in this book. We've changed algorithms, reduced the number of memory allocations, fine-tuned the code, made parts of programs parallel, and more. Sometimes, however, all of this is not enough. Maybe the problem is too hard and we give up, or maybe the fault lies in Delphi; more specifically, in the compiler.

In such cases, we will look outside the boundary of a local computer or company, and search the internet for a solution. Maybe, somebody has already solved the problem and created a nicely wrapped solution for it. Sometimes, we'll be able to find it. Most of the time, it will not be written with Delphi in mind.

Face it, Delphi programmers (even though there are millions of us) are still a minority in a world of C, Java, and Python. It is much simpler to find a C or C++ solution for hard problems than a Delphi one. This is, however, not a reason to give up. It is always possible—with a bit of hard...
