Learn how to use Go's singleflight and errgroup packages, and other important design patterns for concurrency, with real-world examples.

Go is often praised for its fast build times. While they are pretty quick, they are slow enough that I spend a lot of time waiting for them, enough that it prompted me to go down the rabbit hole of thoroughly analyzing them. This post covers all aspects of what makes Go builds fast or slow. Throughout this blog, we will use Istio as an example of real-world codebase. For reference on its size:

Intro Profile-Guided Optimization (PGO) is an optimization method which improves final compiled binary by using profile data hints and compiling the code based on those profiles. There are several optimization mechanisms that compilers usually get into account when compiling your code to binary. Like dead code elimination, Register allocation, Constant folding or function inlining; you may split your code into smaller and smaller functions and different level of abstractions to ease up future changes and modifications, but from compiler point of view multiple calls to different functions may not be very optimize and sometimes compiler decides to inline your functions!

Looking for a standard Go project layout? Careful: Different projects have different needs. Find the best project layout for your Go project type.

Map is a built-in type that acts as a key-value storage. Unlike arrays where you’re stuck with keys as increasing indices like 0, 1, 2, and so on, with maps, the key can be any comparable type.

In the One Billion Row Challenge, the task is to write a program capable of reading an 1-billion-line file (with around 13GB), process and aggregate temperature readings from various weather stations, and present a report of the results on console. In this article, I share my experience attempting the challenge with Golang, providing the details of how I achieved 1.96 seconds.

The article discusses about Golang memory allocation inside structs and how it can be optimized for better performance.
