A common task in Go API design is returning a byte slice. In this post I will explore some old techniques and a new one. In particular, we'll see how the mid-stack inliner interacts with escape analysis to make it possible for the most natural API to be also…

Learn how to visualize CPU samples from Go execution traces with FlameScope.

Or, speeding up writing binary data in Go by 14x. Code here.

Google's Go compiler and runtime team meets periodically (roughly weekly) to discuss ongoing development of the compiler and runtime. While not open to the public, there's been desire by th...

Initial release of SwissMap, a Golang port of Abseil's flat_hash_map.

This blog post is an exploration of JSON parser performance, and, ultimately, a description of the high-performance JSON parser used in CockroachDB.

The sha_ni sha256 instructions have been shown to provide an ~4x increase in hash rate on newer amd64 systems versus the avx2 implementation. Transliterating the Linux implementation shows an up to...

Building a database from scratch is no small feat. Doing so in Go might just be pure madness. In this talk, Co-Founder & CTO Etienne Dilocker highlights the unique challenges and their creative solutions that our development team encountered while building…

Discover how Tailscale achieved over 10Gb/s throughput on Linux using advanced UDP segmentation and checksum optimizations. Explore benchmarks, results, and the innovations powering wireguard go's latest performance leap.

Explore common causes of memory leaks in Go and learn to use Grafana Pyroscope, an open source continuous profiling solution, to find and fix these leaks.

Currently the compiler groups expressions with commutative operations such as a + b + c + d as so: (a + (b + (c + d))) which is suboptimal for CPU instruction pipelining.
This pass balances commuta...

An in-depth analysis of the assembly code emitted by the Go compiler for function calls on arm64.
