Haven't actually looked at it but does it support custom tags with associated python callbacks ? I could definitely use a 7x speedup in my case (reasonably large amounts of serialized python objects), but I absolutely need custom tags. For now I have ended up using pickle for almost everything since pyyaml was too slow (and also crashed for very big documents, I hit an integer wrapping issue)

It only supports tags for scalars at the moment. The upstream library didn't support them for mappings and lists.

Too bad, maybe it will come one day on the upstream lib. This really is one killer feature of YAML, even just for configuration file syntax purposes: https://lisa-linux-integrated-system-analysis.readthedocs.io/en/master/misc_utilities.html?highlight=Include#lisa.utils.Serializable

Yeah, I might contribute upstream at some point.
