When GTS is running in a container runtime which has configured CPU or memory limits or under an init system that uses cgroups to impose CPU and memory limits the values the Go runtime sees for GOMAXPROCS and GOMEMLIMIT are still based on the host resources, not the cgroup. At least for the throttling middlewares which use GOMAXPROCS to configure their queue size, this can result in GTS running with values too big compared to the resources that will actuall be available to it. This introduces 2 dependencies which can pick up resource contraints from the current cgroup and tune the Go runtime accordingly. This should result in the different queues being appropriately sized and in general more predictable performance. These dependencies are a no-op on non-Linux systems or if running in a cgroup that doesn't set a limit on CPU or memory. The automatic tuning of GOMEMLIMIT can be disabled by either explicitly setting GOMEMLIMIT yourself or by setting AUTOMEMLIMIT=off. The automatic tuning of GOMAXPROCS can similarly be counteracted by setting GOMAXPROCS yourself.

# Contributing to go-units
|
|
|
|
Want to hack on go-units? Awesome! Here are instructions to get you started.
|
|
|
|
go-units is a part of the [Docker](https://www.docker.com) project, and follows
|
|
the same rules and principles. If you're already familiar with the way
|
|
Docker does things, you'll feel right at home.
|
|
|
|
Otherwise, go read Docker's
|
|
[contributions guidelines](https://github.com/docker/docker/blob/master/CONTRIBUTING.md),
|
|
[issue triaging](https://github.com/docker/docker/blob/master/project/ISSUE-TRIAGE.md),
|
|
[review process](https://github.com/docker/docker/blob/master/project/REVIEWING.md) and
|
|
[branches and tags](https://github.com/docker/docker/blob/master/project/BRANCHES-AND-TAGS.md).
|
|
|
|
### Sign your work
|
|
|
|
The sign-off is a simple line at the end of the explanation for the patch. Your
|
|
signature certifies that you wrote the patch or otherwise have the right to pass
|
|
it on as an open-source patch. The rules are pretty simple: if you can certify
|
|
the below (from [developercertificate.org](http://developercertificate.org/)):
|
|
|
|
```
|
