Swiss Maps in Go - Bryan Boreham

Did you know that the 'map' type has a whole new implementation as of Go 1.24? Originally created in 2016 as a C++ library, Swiss Map uses ingenious bit-manipulation techniques to get more throughput from your CPU. We'll cover: How does it work? New SIMD (single-instruction, multiple-data) support in the compiler. CPerformance results from real-world applications. Gotchas and caveats. Bryan Boreham, Distinguished Engineer at Grafana Labs, returns with his extensive knowledge giving us a talk on Swiss Maps at GopherCon UK 2025 held on 14-15th August. #gopherconuk #golang #goprogramming #datastructures #performanceengineering #highperformancecomputing #cloudnative #techtalk #golanguage
