Documentation takes too long to build about satpy

Ah there is a -j option to specify sphinx number of jobs.

As expected if I comment out the html += map_section(area) portion of the HTML formatting in pyresample the HTML list of areas is generated in less than a second. So purely cartopy map generation here.

Is it possible to generate those maps in parallel?

[djhoese]

Good idea. Probably. Right now this all happens as a side effect of sphinx loading the conf.py configuration file. To make it a little cleaner with fewer unintended consequences we should probably put this in a sphinx extension module to be loaded by sphinx specifically. I've done this for "roles" used in the .rst files, but never any of the other types of extensions. Actually, now that I say that I wonder if sphinx has a parallel build plugin available...
