Hi Brian, If you are making changes in this area, then something that would be really helpful is providing more fine grained control over which facts are collected (currently gather_subset), and which are stored (filter). The gather_subset is quite coarse grained, and filter is only really usable if you are wanting to refresh one or more similarly named facts.
To provide some context, I have been spending a lot of time recently trying to improve the performance of Ansible at a moderate (~200) scale. As I'm sure you're aware, facts are a *huge* source of slowness, taking us from a baseline of 2 seconds to execute a task to 30+ seconds. In our particular case the target hosts are the controllers and hypervisors in an OpenStack cloud. On these machines there can be many virtual network interfaces, each creating a large fact. Our current solution looks like this: filter: "ansible_[!qt]*" Which removes the virtual interfaces that begin with q or t. We are lucky to not be filtering out any useful facts with this. A more flexible system such as a list of regexes would be a big help.
