How does Go's garbage collector handle memory allocation in concurrent programs?

16 Eyl 10:00

Go's garbage collector is designed to work with its lightweight goroutine model, but I'm not clear on the exact mechanics. How does the GC identify and reclaim memory when many goroutines are running simultaneously? Does it pause all goroutines, or use a concurrent marking phase? Also, what are the typical performance trade‑offs developers should be aware of when tuning GC parameters in high‑throughput services?
