Looking at this mur-sst dataset in particular, it stores time in chunks of size 5. That means fetching the 6443 time values requires 1288 separate HTTP requests -- no wonder it's so slow! If the time axis were instead stored in a single chunk of 51 KB, Xarray would only need 3 small size HTTP requests to load the lat, lon and time indexes, which would probably complete in a fraction of a second.

That said, I agree that this would be nice to have in general.
