I noticed you set the compression options for xz to -9. I'm not sure this is a good idea, with -9 xz will use 674MB of memory - even for files that are smaller than that (a 100MB file used 674MB, and a 3.3MB file used 139MB, but it probably varies depending on content).
I think you should not set any number, and let xz decide on the default (which is currently -6, which has a max of 94MB).
Is it realistic to take another option (1-9) to pass to the compressor if people want to change it?
BTW thanks for implementing this so fast! -Ariel -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
