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

Parallel programming with .NET TPL


We have a basic knowledge of asynchronous, parallel asynchronous, and interoperability of asynchronous workflows with .NET EAP and APM. We have finished discussing .NET Task based Asynchronous Programming (TAP) in the form of interoperability between F# asynchronous workflows and .NET TAP. We are now discussing more about interoperability with .NET TPL.

F# does not just have its own implementations of asynchronous supports and parallel asynchronous but is fully compatible with .NET BCL hence .NET TPL.

.NET TPL is not just an infrastructure of a combination of implied asynchronous and parallelism. It focuses on these three features:

  • Task-based parallelism

  • Data parallelism

  • PLINQ, an implementation of LINQ in parallel, also called Parallel LINQ

Let's learn more .NET TPL by visiting the MSDN Library .NET TPL landing page:

According to MSDN, this is the overall high-level picture of .NET 4 TPL:
