-ODP: [Bug-tar] GNU tar, star and BSD tar speed comparision +new script
-
-Jan Psota
-Thu, 25 Oct 2007 06:51:13 -0700
-
-Latest TCP script at the bottom (3180 bytes).
-4 tests: 64bit dual core Athlon tmpfs / disk (reiserfs) - 60MB/s,
- 32bit Athlon tmpfs / disk (reiserfs) - 55MB/s
-Both machines were idle -- used for testing only.
-Tarball and extracted files were on different physical devices.
-Test data: linux 2.6.22/3 kernel sources for memory operations,
-for the other data average file size should bring enough info.
-
-2 x [...] processor means 1 processor with 2 cores (2 entries in cpuinfo).
-Archive format is set to pax (Joerg).
-Let's end with it. I only wanted to send You a new version of TCP script :-).

-TCP stands for Tar Comparision Program here.
-It currently compares: BSD tar (bsdtar), GNU tar (gnutar) and star in archive
-creation, listing, extraction and archive-to-extracted comparision.
-Tcp prints out best time of n=$n repetitions.
-
-Tcp creates temporary archive named tcp.tar with $pax and some native
-(--seek/-no-fsync) options and extracts it to [\$3]/tcptmp/.
-If unset, third argument defaults to [\$2].
-After normal exit tcp removes tarball and extracted files.
-Tcp does not check filesystems destination directories are on for free space,
-so make sure there is enough space (a bit more than source_dir uses) for both:
-archive and extracted files.
-Do not use white space in arguments.
