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

Quick overview of generic type support in F#


F# has generic type as the parameterized type support, just as in C#/VB, and all have the same concept and similar semantics, although F# goes further by allowing type generalizations.

For example, in F#, to declare a type that has a generic type parameter in use:

List<'t> 

If the parameter is used in code, the parameter of the generic type must be filled in, such as in this example:

List<int> 

In our last example, the generic type becomes specialized as int. The List is a sample of a concrete type that has a generic type as the type parameter. This concept is also similar to the semantics in C#/VB.

Note

Throughout this book, the types in F# that support the generic type such as F# List, Map, Set, and Array will use the same notation as F# types in the MSDN Library, although the complete compilation name may differ. For example, F# Map type is known as FSharpMap from outside of F#'s scope (when used in other languages such as...
