For mksquashfs from squashfs-tools 1:4.3-11 , I ran it by: > time sudo mksquashfs squashfs-root filesystem.squashfs.new -b 1024k > -comp xz -Xbcj x86 -e boot -no-progress Is there any way I can generate that set of files / directory you are using for mksquashfs? Anyway, please try the upcoming squashfs-tools package release[1] and report back to me. Indeed it is slower than -9 on my data, but only around 20%.
