Analysis show that for large catalog YAML dumping consumes lots of memory (roughly 3x times the object to serialize). The catalog is sent from the master to the client in serialized format (usually pson/json), the idea would be to directly use it as the local client cache, instead of re-serializing the "live" catalog. One possible implementation would be: * keep the serialized version of the catalog in the request in the REST client * when caching the catalog, have a specific terminus that would just dump this string to disk This has been regularly observed in the field as being a significant performance cost, especially when performing interactive Puppet runs to debug issues interactively. -- You have received this notification because you have either subscribed to it, or are involved in it.
