We use gz for compatibility and xz for increased compression ratio/decompression speed. $ rpm -q xz gzip bzip2 xz-4.999.9-0.1.beta.20091007git.fc11.i586 gzip-1.3.12-10.fc11.i586 bzip2-1.0.5-5.fc11.i586 $ bzip2 -dc linux-2.6.33-rc7.tar.bz2 | xz > linux-2.6.33-rc7.tar.xz $ xz -dc linux-2.6.33-rc7.tar.xz | gzip > linux-2.6.33-rc7.tar.gz $ l -rw-rw-r-- 1 padraig 66,191,954 Feb 6 22:27 linux-2.6.33-rc7.tar.bz2 -rw-rw-r-- 1 padraig 56,347,392 Feb 9 11:17 linux-2.6.33-rc7.tar.xz -rw-rw-r-- 1 padraig 85,300,209 Feb 9 11:20 linux-2.6.33-rc7.tar.gz $ time bzip2 -dc linux-2.6.33-rc7.tar.bz2 >/dev/null real 0m30.132s $ time gzip -dc linux-2.6.33-rc7.tar.gz >/dev/null real 0m4.996s $ time xz -dc linux-2.6.33-rc7.tar.xz >/dev/null real 0m11.003s cheers, P?draig. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
