If it were "only" the Amanda server, I could go all out with pigz. However, it is also the
department server and runs mail, web, samba, printing, etc. If I were to top out all the cores with
pigz, I would have everyone in the department complaining about performance on other services.

In your setup, are there enough DLEs to compress that Amanda can keep
all your cores busy with gz processes working on different DLEs?
Or do you have some cores underutilized, that you could maybe bring
into the game by using pigz instead of gz?
