40ms Go garbage collector pause traced to swap
Original: A 40ms Go garbage collector pause caused by swap
An engineer has documented how a Go application suffered a 40ms garbage collector pause, tracing the cause to swap activity on the machine. The writeup explains that when memory pressure pushes Go runtime pages to swap, garbage collection can stall far beyond its usual microsecond pause targets. Readers are debating the runtime's interaction with the operating system's memory management.
Why now: Go developers are interested in unexpected GC latency spikes and their obscure OS-level causes.
