go-performance

What problem does it solve?

This Skill guides Go developers to reduce allocations, optimize string processing, and streamline I/O to achieve faster, more memory-efficient applications.

Core Features & Use Cases

• Memory allocation reduction: patterns and idioms that minimize allocations and GC pressure.
• Efficient string building: using strings.Builder to avoid O(n^2) string concatenation.
• Pooling and re-use: applying sync.Pool to reuse objects and reduce churn.
• Buffered I/O: employing bufio and buffered writers/readers to lower syscalls.
• Benchmarking focus: measuring improvements to validate optimizations with repeatable tests.

Quick Start

Apply these practices to an existing Go function by replacing repeated string concatenations with a strings.Builder, wrap frequently allocated objects with a sync.Pool, and switch to buffered I/O where appropriate.
