F# High Performance

By: Eriawan Kusumawardhono

Overview of this book

F# is a functional programming language and is used in enterprise applications that demand high performance. It has its own unique trait: it is a functional programming language and has OOP support at the same time. This book will help you make F# applications run faster with examples you can easily break down and take into your own work. You will be able to assess the performance of the program and identify bottlenecks. Beginning with a gentle overview of concurrency features in F#, you will get to know the advanced topics of concurrency optimizations in F#, such as F# message passing agent of MailboxProcessor and further interoperation with .NET TPL. Based on this knowledge, you will be able to enhance the performance optimizations when implementing and using other F# language features. The book also covers optimization techniques by using F# best practices and F# libraries. You will learn how the concepts of concurrency and parallel programming will help in improving the performance. With this, you would be able to take advantage of multi-core processors and track memory leaks, root causes, and CPU issues. Finally, you will be able to test their applications to achieve scalability.

Preface

Chapter 7. Language Features and Constructs Optimization

When we code, it happens quite often that we are sunk into optimization details. We often have to focus on dealing with concurrency, performance/benchmark measurements, and profiling other elements such as memory consumptions. This focus on concurrency and performance/benchmark measurements is, of course, a big and important element of our code, especially concurrency. This topic has been described extensively in the previous two chapters: Chapter 4, Introduction to Concurrency  in F# and Chapter 5, Advanced Concurrency Support in F#.

There are other elements in F# to be recognized as optimization opportunities, the language constructs that are commonly used in code and also advanced language constructs such as computation workflow. Language constructs, including the combination of semantics and syntax, are crucial too because we are directly dealing with them as we code. This chapter is dedicated to identifying performance optimizations...
