This was not selected, but I found the bottle-neck: in the same tab, the
template was set to "To remove" instead of "Do not change".  Using "Do
not change" makes things fast, so thanks for pointing me to this part of
the configuration :-)

I rather use my RAW files when I wish lossless operation (and save the
result as PNG).  But having JPEG is handy to share files quickly with
friends.
