mesh - generating face groups is very time consuming but doesn't appear to use full CPU potential

[jrichels20]

Hello.  A friend sent me a mesh model that has entirely rounded surfaces.  His seat is Free and I gather could not perform a mesh conversion, mine is paid.  The process of generating faces took a long time, several hours (I don't know exactly as it ran over-night).   I noticed that the processor utilization was not that high, less than 20% and only about 12GB of memory, that on a Ryzen 7 5800X (8 cores).  Is there any way to speed up this process?

Thank you.

I don't think there is any way to speed this up.

Can you share a screenshot of the object?

If "mostly rounded surfaces" means "organic", then creating face groups is not needed.
