.... Those are compression times? What about the much more important decompression times at boot?
Compression: opensuse.tar 179087360 It is about 170 MB of email messages, in other words mostly text. $ time xz -kz opensuse.tar real 1m20.960s user 1m20.477s sys 0m0.229s opensuse.tar.xz 18859460 (about 18 MB = 60% ) $ time bzip2 -zk9 opensuse.tar real 0m31.556s user 0m31.407s sys 0m0.121s opensuse.tar.bz2 23718197 (about 22.6 MB = 75.7% ) $ time gzip -9 opensuse.tar real 0m7.590s user 0m7.495s sys 0m0.091s opensuse.tar.gz 31332269 (about 30 MB = 100% ) Decompression: $ time xz -d opensuse.tar.xz real 0m2.626s user 0m2.377s sys 0m0.247s $ time bzip2 -d opensuse.tar.bz2 real 0m6.336s user 0m6.025s sys 0m0.302s $ time gzip -d opensuse.tar.gz real 0m1.226s user 0m1.023s sys 0m0.201s File size: xz > bzip2 > gzip Compression time: gzip > bzip2 > xz Decompression time: gzip > xz > bzip2 I was playing with compression ratio (0)1-9, but did not have time to sort results. -- Regards, Rajko. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
