Observing Go's garbage collector, old and new

This article discusses Go 1.25's introduction of the Green Tea garbage collector and its default status in Go 1.26. It recaps the collector's features, examines programs that benefit most, and highlights limitations like the non-moving collector's inability to reclaim sparse pages. The author compares Go's size-segregated memory allocation with C#'s, using examples of random object allocations to demonstrate heap behavior. The content is technical, focusing on garbage collection, memory management, and performance implications in Go, making it relevant to IT/technology professionals interested in programming languages and runtime internals.
