** Description changed: Binary package hint: file-roller file-roller should use the 7z program (from the package p7zip-full) to decompress bzip2 archives, becauase it is faster than the bzip2 program itself. Get 100MB from /dev/urandom and compress it, one copy using bzip2 -1 and one using bzip2 -9, then make a copy of each of these. You should not have 4 bzip2 archives, each about 100MB (because urandom doesn't compress well). Extract one of each with 7z (7z x archive.bz2) and one with bzip2 (bunzip2 archive.bz2). Note how long it takes to extract. For me it was: Compressed with -1: bunzip2: 38 seconds 7z: 27 seconds Compressed with -9: bunzip2: 52 seconds 7z: 34 seconds. If you pull the data from /dev/zero rather than /dev/urandom, all come to 2 seconds, so no difference. + + + Version info: + [EMAIL PROTECTED]:~$ apt-cache policy bzip2 p7zip-full + bzip2: + Installed: 1.0.4-0ubuntu1 + Candidate: 1.0.4-0ubuntu1 + Version table: + *** 1.0.4-0ubuntu1 0 + 500 http://gb.archive.ubuntu.com gutsy/main Packages + 100 /var/lib/dpkg/status + p7zip-full: + Installed: 4.47~dfsg.1-1 + Candidate: 4.47~dfsg.1-1 + Version table: + *** 4.47~dfsg.1-1 0 + 500 http://gb.archive.ubuntu.com gutsy/universe Packages + 100 /var/lib/dpkg/status + [EMAIL PROTECTED]:~$
