Topic: ✔ xr.concat taking too long

view this post on Zulip Erin Dougherty (Aug 22 2023 at 19:14):

Hi all! I am wondering if someone can help me speed up xarray.concat() to combine a list of xarray.DataArrays() into one DataArray. It should be fairly fast, since my list of DataArrays is only 2 elements, and each DataArray has small chunks (see screenshot below). Do you have any tips? Thanks!

I forgot to mention, but performing xr.concat() for this takes over an hour, which seems excessively long!
