Use libyaml parsing when available
Nodepool periodically reloads its config. On systems with large
configs this can cause a substantial amount of cpu usage. Our
profiling of an idle provider revealed that the yaml parsing accounted
for ~15% cpu load while the provider was idle.

This could be improved by utilizing the native libyaml bindings when
available.

Nodepool

Nodepool is a system for managing test node resources. It supports launching single-use test nodes from cloud providers as well as managing access to pre-defined pre-existing nodes. Nodepool is part of a suite of tools that form a comprehensive test system, including Zuul.

The latest documentation for Nodepool is published at: https://zuul-ci.org/docs/nodepool/

The latest documentation for Zuul is published at: https://zuul-ci.org/docs/zuul/

zuul-discuss

General discussion about Zuul, including questions about how to use it, and future development.

You will also find Zuul developers in the #zuul channel on Freenode IRC.
