Go's GC: A Deep Dive and a Custom Arena Allocator

This article delves into the intricacies of Go's garbage collection and leverages that knowledge to build a high-performance arena allocator. By cleverly exploiting Go's GC behavior, the author achieves faster memory allocation than Go's built-in allocator, especially for large-scale allocations. The article details the design principles, implementation, and benchmark results of the custom arena allocator, also analyzing its performance in high-concurrency environments.
