40ms Go garbage collector pause traced to swap
Original: A 40ms Go garbage collector pause caused by swap
An engineer has documented how Linux swap caused an unexpectedly long 40-millisecond pause in Go's garbage collector, well above the usual sub-millisecond target. The write-up walks through diagnosing the latency spike and shows how swapping memory pages can stall the collector. Developers running latency-sensitive Go services are discussing tuning swap and memory settings to avoid similar pauses.
Why now: Latency-sensitive Go developers are closely examining garbage collector pauses and their unexpected system-level causes.
