This book provides some code performance optimization
tricks, tips, and suggestions. Most of the contents in this book
are made based on the official standard Go compiler and
runtime implementation.Life is full of trade-offs, the
programming world is, too. In programming, we often need to
make trade-offs between code readability, maintainability,
development efficiency, and program efficiency, etc. Even for
one of the aspects, there are also trade-offs needing to be
made. Taking program efficiency for an example, we might
need to make trade-offs between memory saving, code
execution speed, and implementation difficulty, etc.In practice,
most parts of the code base of a project don't need to be
implemented with high performances. Keeping them
maintainable and readable is often more important (than
making them memroy saving and run very fast). The
suggestions made in this book are just for the code parts
which implementations really need to be high performant.
Some of the suggestions often causes more verbose code.
And please note that some of the suggested implementation
might only be performant at some certain scenarios, and might
be not at others.The contents in this book include: how to
consume less CPU resources. how to consume less memory.
how to make less memory allocations. how to control memory
allocation places. how to reduce garbage collection
pressure.This book neither explain how to use performance
analysis tools, such as pprof, nor try to study deeply on
compiler and runtime implementation details. None of the
contents provided in this book make use of unsafe pointers

and cgo. The contents in this book also doesn't talk about
algorithms. In other words, this book tries to provide some
optimization suggestions in a way which is clear and easy to
understand, for daily general Go programming.
