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

General computation expression design considerations


We have implemented a very simple computation expression using Bind, Return, and Zero as a starting sample.

We can conclude that the use of Bind will translate into let! as the result of let! expression will be composed nicely. The other translations are available on the official MSDN docs page of computation expression.

The translation of builder methods into syntaxes of language constructs such as let!, return, return!, and  do! are samples of syntactic sugar. The syntactic sugar of a computation expression is the ability to translate the builder methods into very neat declarative expressions to combine expressions and functions nicely. It is quite easier to have computation expressions instead of directly calling the method builder after instantiating the builder object's constructor.

Based on the discussion in the previous sections, we have concluded that there are some aspects of best practices and some advice that must be taken into...
