# GOGCTuner

idea is from this article [How We Saved 70K Cores Across 30 Mission-Critical Services (Large-Scale, Semi-Automated Go GC Tuning @Uber) ](https://eng.uber.com/how-we-saved-70k-cores-across-30-mission-critical-services/)

## How to use this lib?

just call NewTuner when initializing app :

```go

func initProcess() {

	var (

		inCgroup = true

		percent = 70

	)

	go NewTuner(inCgroup, percent)

}

```

## Current Status

Go 1.19 adds a [soft memory limit](https://github.com/golang/proposal/blob/master/design/48409-soft-memory-limit.md) which changes its pacer algorithm and scvg behavior, we'll see what go team will provide in the new version. Maybe this lib can be deprecated in Go 1.19.
