Package: tar Version: 1.20-1 Severity: normal When running "tar tf" on a large tarball containing few large files, tar becomes incredibly slow. The reason for this is that tar issues many read()s to skip the file content, but as it doesn't need the content, it throws it away. GNU tar could just use lseek() like libarchive and busybox do.
Also a problem is extracting only one file from said tarball, where the other files do not need to be read for just that one to be extracted. The problem exists on all versions of GNU tar and was confirmed to exist on at least all versions starting from etchthe one shipped with Etch. -- System Information: Debian Release: 5.0.2 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 2.6.26-2-amd64 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages tar depends on: ii libc6 2.9-12 GNU C Library: Shared libraries tar recommends no packages.
