Yes, I'm on 0.11.

Nothing displays on the task stream/ progress bar when using open_mfdataset, although I can monitor progress when, say, computing the mean.

The output from %time using decode_cf = False is CPU times: user 4.42 s, sys: 392 ms, total: 4.82 s Wall time: 4.74 s

and for decode_cf = True: CPU times: user 11.6 s, sys: 1.61 s, total: 13.2 s Wall time: 3min 28s

Using xr.set_options(file_cache_maxsize=1) doesn't make any noticeable difference.

If I repeat the open_mfdataset for another 5 files (after opening the first 5), I occasionally get this warning: distributed.utils_perf - WARNING - full garbage collections took 24% CPU time recently (threshold: 10%)

I only began using the dashboard recently; please let me know if there's something basic I'm missing.
