How the Go runtime implements maps efficiently without generics
This post discusses how maps are implemented in Go. It is based on a presentation I gave at the GoCon Spring 2018 conference in Tokyo, Japan.

Visualising the Go garbage collector
gcvis is a simple way of visualising the operation of the garbage collector within a Go process. Here is a screenshot of it in operation. The rest of this article explores how gcvis works and how to interpret its results.

A whirlwind tour of Go’s runtime environment variables
The Go runtime, in addition to providing the usual services of garbage collection, goroutine scheduling, timers, network polling and so forth, contains facilities to enable extra debugging output and even alter the behaviour of the runtime itself.

Building a high performance JSON parser
JSON is important, damn near everything that we do as programmers or operators involves JSON at some point. JSON decoding is expensive, if your product talks JSON then performance of marshalling data in and out of JSON is important. This is a talk about designing an efficient replacement for encoding/json.Decoder .

This is a post about performance. Most of the time when worrying about the performance of a piece of code the overwhelming advice should be (with apologies to Brendan Gregg) don’t worry about it, yet. However there is one area where I counsel developers to think about the performance implications of a design, and that…
