And just want to point out that the stacktraces/profile look very different between 2022.3.0 and main/latest. Looks like https://github.com/pydata/xarray/blob/021c73e12cccb06c017ce6420dd043a0cfbf9f08/xarray/core/indexes.py#L185 might be fairly expensive operation. Separately there seem to be quite a bit of time spend in copy -> copy_indexes path (deep copy?).
