Building pyramids gobbles up heaps of disk space. I tried pyramids on
157 MB layer, which created an extra file 1.6 GiB.
I can't see the WMTS building lots of temporary file pyramids using up disk

Hi Patrick,
Sorry for asking, did you create pyramids (overlays) for your raster
"tiles"?
See more information about pyramids on QGIS official documentation:
https://docs.qgis.org/3.4/en/docs/user_manual/working_with_raster/raster_properties.html#pyramids-properties
To create pyramids on many files, it's probably better to use GDAL
directly to process all files in a folder:

My feeling is that the WMS service is doing that for you, and that's
the reason why it works well with a service.
