After looking for all compression tools that were also parallel I found the following: PXZ - Parallel XZ is a compression utility that takes advantage of running LZMA compression of different parts of an input file on multiple cores and processors simultaneously. Best to have a habit of using -d or -decompress instead of unxz as well. 9 Answers Sorted by: 84 Well, the keyword was parallel. The docs recommend this in case you are using this for scripting. What I am doing: XZOPT-T0 -9 -vv tar -vvcJf /. It will only work on files that contain multiple blocks with size information in block headers. To quote the xz man-pages: Threaded decompression hasn't been implemented yet. Note: unlike Rafael's answer, use xz -dc instead of catxz. 1 Normally, compression is the bottleneck, such that threaded decompression is not supported by most compression libs. To echo Rafael van Horn, to uncompress & untar (see note below): xz -dc | tar x z to manually set xz to zip, though it defaults to zipping if not otherwise directed. I often use -k to -keep the original file and -9 for really heavy compression. Where -4e is, use your own compression options. > directs the tarred and compressed file to.7-Zip now can use multi-threading for xz decoding, if there are multiple. xz -4e calls xz with the -4e compression option. 7-Zip now can create TAR archives in POSIX (pax) tar format with the switches.f reads from a directory (best to put this second because -cf != -fc).
Tar xz multithreaded archive#
c creates a new archive for the specified files.Tar cf - filename | xz -4e > īecause I liked Wojciech Adam Koszek's format, but not information: If you want to use compression options for xz, or if you are using tar on MacOS, you probably want to avoid the tar -cJf syntax.Īccording to man xz, the way to do this is:
