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.

Most common problems


Before we start writing multithreaded code, I'd like to point out some typical situations that represent the most common sources of problems in multithreaded programs. After that, I'll look into the possible ways of solving such situations.

The biggest problem with the situations I'm about to describe is that they are all completely valid programming approaches if you are writing a single-threaded code. Because of that, they sometimes slip even into (multithreaded) code written by the best programmers.

As we'll see later in the chapter, the best way to work around them is just to stay away from problematic situations. Instead of data sharing, for example, we can use data duplication and communication channels. But I'm getting ahead of myself ...

All of the situations I'm going to describe have something in common. They are a source of problems that can stay well hidden. Lots of times, parallel programs seem to be working during the testing but then randomly fail only at...
