At least on my laptop from 2015, its was longer than 1s:

[ 25.00%] ··· Running unstacking.Unstacking.time_unstack_fast  201.44ms
[ 50.00%] ··· Running unstacking.Unstacking.time_unstack_slow  5.75s
[ 75.00%] ··· Running unstacking.UnstackingDask.time_unstack_fast 1.35s
[100.00%] ··· Running unstacking.UnstackingDask.time_unstack_slow 7.39s

so I reduced the array size and now its

[ 25.00%] ··· Running unstacking.Unstacking.time_unstack_fast  26.33ms
[ 50.00%] ··· Running unstacking.Unstacking.time_unstack_slow   594.61ms
