Alright. I think we’ve beat the proverbial dead horse here. The devs
know this is a request and they will get it into their dev queue for
examination.
I saw that clamd use just one core at a time to load the databases.

Why not using half of the cores to also reduce the loading time? Many
years ago when I used eMule for downloading big files, I was so
fascinated by the download mechanism: one big file, many download
sources to get the file together piece by piece. And it didn't have to
follow any order. That would be fun to programm for loading the
databases, am I right? :-)
