I posted some figures here: https://lists.gnu.org/archive/html/guix-devel/2020-04/msg00374.html. Here's a more complete summary: --8<---------------cut here---------------start------------->8--- | | Host (wip-disk-image) | VM (master) | |----------------+-----------------------+-------------| | No compression | 4min | 12min | | Compression | 8min | 19min | --8<---------------cut here---------------end--------------->8--- > When I added zlib compression I was surprised to learn that here it made no > significant difference in wall clock time (less than a minute; 5% or so) or > CPU time. The disks they spin and CPU she is fast, but still I would have > noticed a spike. Strange we have different results, those benches are not very accurate though. Thanks, Mathieu
