Exploring the use of SIMD in Golang by running assembly directly, this post discusses the potential performance improvements and challenges. The Go assembler, Plan 9 based, allows writing of intermediate code before compiling to architecture-specific objects, with notable performance boosts as seen in projects like Apache Arrow. Examples from various sources, such as Go's own source code and production code from Segmentio, illustrate practical applications. While fun and insightful, writing assembly for Go can be complex and is recommended for specialized use cases rather than general projects.
