Description

Performance matters! Users hate to use programs that are not responsive to interactions or run too slow to be useful. While becoming a programmer is simple enough, you require dedication and hard work to achieve an advanced level of programming proficiency where you know how to write fast code. This book begins by helping you explore algorithms and algorithmic complexity and continues by describing tools that can help you find slow parts of your code. Subsequent chapters will provide you with practical ideas about optimizing code by doing less work or doing it in a smarter way. The book also teaches you how to use optimized data structures from the Spring4D library, along with exploring data structures that are not part of the standard Delphi runtime library. The second part of the book talks about parallel programming. You’ll learn about the problems that only occur in multithreaded code and explore various approaches to fixing them effectively. The concluding chapters provide instructions on writing parallel code in different ways – by using basic threading support or focusing on advanced concepts such as tasks and parallel patterns. By the end of this book, you’ll have learned to look at your programs from a totally different perspective and will be equipped to effortlessly make your code faster than it is now.

Who is this book for?

This book is for all Delphi programmers. Whether you’re a beginner or an accomplished programmer, you will find something interesting. Even though the focus is on the latest Delphi release, the code uses only standard Delphi syntax without syntactic additions from the latest releases, and most of it should compile and run in any Delphi from XE7 onward. If you’re using an older version of Delphi, don’t despair! Most of the concepts in this book do not depend on a specific Delphi version and will be useful for everyone.

What you will learn

Get to grips with algorithmic complexity and learn how to recognize it
Use tools to determine program runtime behavior
Speed up programs by doing less instead of more
Discover the internal workings of Delphi data structures
Gain an understanding of Delphi's memory manager
Find out how to write low-level parallel programs with TThread
Use parallel patterns from the PPL and OTL libraries to write fast code
Include external code, written in C or C++, in Delphi programs

In all fairness, I haven't worked a lot with Delphi. Most of my work centers deal with platforms. As we bring on more customers, some of the challenges occur in helping those apps run better and they all need better data. This book was perfect in picking and using the right tools and algorithms to do massively parallel processing in finding the right data. I also really liked the emphasis on building observability tools in to make sure one can capture metrics and truly get the best data performance.

Everyone programming with Delphi will need to optimize their programs.Some programs focus on the customer by using a beautiful user interface, showing charts, or delegating tasks to the database.Other programs must solve complex tasks that could make them too slow for practical purposes.This kind of program, limited by the hardware, memory, or size of the problem, can require careful optimization.This book describes program complexity with simple examples.It also shows many ways to improve Delphi code performance.The first step is to discover where your program spends most of its running time. That is profiling. There are several examples of using it on real programs.You can improve performance by using better algorithms.In this book, the author shows how to use one of the best Delphi libraries, Spring4D.Another way to achieve much higher performance is to use parallel programming.Delphi includes the class TThread and several synchronization classes for this kind of scenario.After a detailed analysis, the author extracts some valuable parts of its OmniThreadLibrary to illustrate how to improve what is standard in Delphi.Finally, sometimes it is unnecessary to reinvent the wheel because the solution was already implemented in another language. There is a section about how to link external libraries to Delphi.As the cherry on top, the book finished by describing a good selection of "best practices".This book is the perfect companion for any Delphi developer.All the code used in the book is also in GitHub!Congratulations!

I was asked to be an early reviewer for this book and one of the examples that describes deadlocks was exactly the problem in some parallel code. Primoz gave an introduction and example that filled in the gaps to understand where to look and I solved my problem.I believe every developer would benefit from at least 2 sections of the book but review the table of contents. Some of the sections I will use infrequently so I will choose to skip over the parts that are too complex for me to fully grasp and do not currently apply.The book has very short code snippets, look at the full examples on Github for code that you can actually compile. As stated by the author the book is to focus on a code block, my view is it is something like a course book with homework that you are going to have to review in Delphi. For me it is a good mix of hands-on guided reading and learning.The author writes much like how I imagine a teacher in a classroom to present so there is often a review of what we have learned and what is coming. For me this was a welcome break and a little bit of humor when I imagine him speaking. If you find it annoying, you can simply skip over the 2-3 sentences.I appreciate that @Primož Gabrijelčič took the time to share his knowledge and has updated to a 2nd Edition.

This book covers a wide range of topics, from algorithm improvement to tools for finding slow code and parallel programming. It does a great job of explaining complex concepts in a clear and concise way, and the book is full of practical examples that can help you apply the concepts in your own code.The book covers a wide range of topics. Delphi High Performance covers all of the major areas of performance, so you can get a well-rounded understanding of how to write high-performance code.The demo examples that come with the book are comprehensive and clearly demonstrate the points the author is explaining. He doesn't just talk about the concepts in theory, he shows you how to apply them in your own code. This makes the book very valuable for anyone who wants to improve the performance of their Delphi applications.Overall, Delphi High Performance is an excellent book for Delphi developers who want to learn how to write high-performance code. The book is well-written, informative, and full of practical examples. I highly recommend it to anyone who wants to improve the performance of their Delphi applications.
