automemlimit

> ...includes support for a soft memory limit. This memory limit includes the Go heap and all other memory managed by the runtime, and excludes external memory sources such as mappings of the binary itself, memory managed in other languages, and memory held by the operating system on behalf of the Go program" Of course it’s a runtime setting, it won’t affect other factors but you can’t say it didn’t solved anything “because there’s a GitHub issue open” Then Go runtime was unpredictable because of its ideology “CPU is unlimited but not Memory” and containers are kinda of a dynamic resource allocated but it did solve vast amount of problem dealing with kernel OOM and unpredictable GC cycles > You still need to use a helper library like https://github.com/KimMachineGun/automemlimit or https://github.com/uber-go/automaxprocs.

AFAIK, the basic issue is still open at https://github.com/golang/go/issues/33803 and https://github.com/golang/go/issues/59715. You still need to use a helper library like https://github.com/KimMachineGun/automemlimit or https://github.com/uber-go/automaxprocs. Go 1.19 only had this in its notes for memory changes "...includes support for a soft memory limit. This memory limit includes the Go heap and all other memory managed by the runtime, and excludes external memory sources such as mappings of the binary itself, memory managed in other languages, and memory held by the operating system on behalf of the Go program" Forgot to add: The JVM does this for you since JDK 17 https://developers.redhat.com/articles/2022/04/19/java-17-wh...

GOMEMLIMIT has really cut down on the amount of time I’ve had to spend worrying about the GC. I’d recommend it. Plus, if you’re using kubernetes or docker, you can automatically set it to the orchestrator-managed memory limit using something like https://github.com/KimMachineGun/automemlimit — no need to add any manual config at all.

Besides GOMAXPROCS there's also GOMEMLIMIT in recent Go releases. You can use https://github.com/KimMachineGun/automemlimit to automatically set this this limit, kinda like https://github.com/uber-go/automaxprocs.
