Fedora 31 Considers Compressing Their RPM Packages With Zstd Rather Than XZ

man xz gives me this:
Currently the only threading method is to split the input into blocks and compress them independently from each other. The default block size depends on the compression
level and can be overriden with the --block-size=size option.
Threaded decompression hasn't been implemented yet. It will only work on files that contain multiple blocks with size information in block headers. All files compressed in multi-threaded mode meet this condition, but files compressed in single-threaded mode don't even if --block-size=size is used.Last edited by shmerl; 30 May 2019, 11:43 PM.

Big yes! zstd is so fast at decompression. I use it for pretty much everything!
Optimistic merging time please!
Edit: there are the 2 types of Fedora users. The one type who likes to run dnf update while the system is running, so then it's much safer when files are more quickly replaced. Like your Firefox or LibreOffice, or what have you. The second group is the people who select the option "install updates on poweroff" or whatever that was in the Workstation edition, and with zstd they can select that option on their laptops and put the laptop in their bags because the update process takes much shorter. For the ones who do that on a desktop computer it means the fans go off quicker at the end of the day.Last edited by Compartmentalisation; 31 May 2019, 10:01 AM.
