Demo takes 2.5+ hours / garbage collection warnings

[shraddhapai]

Hi, I'm trying to run the demo from the Nature Protocols paper https://www.nature.com/articles/s41596-020-0336-2 using the Dockerized SCENIC. The call to SCENIC has taken about 2.5 hours at this point and is still running.
Is this expected?

Not sure if this is related, but I have 20+ of these warnings on the screen:
"distributed.utils_perf - WARNING - full garbage collections took 10% CPU time recently (threshold: 10%)"

Running on an Ubuntu 18.04 with 32 cores and 128GB RAM.

Any guidance would be great, thanks in advance.
