It would only be worth using gzip (or any form of lossless compression) if the original data is of the type that can take it. It is also worth pointing out that is you "pointlessly" use a compression like gzip on a very large file where there is no usable compression that you simply slow down the process of getting to the data as you have to run the whole thing though unzip which at the very least needs 2 x the disk space. I am very much against using the tape-archive format for files in torrents. Most BitTorreent clients allow you to select and prioritise on a file-by-file basis using the format based on th .torrent file "filesystem header". If you have just one .tar file, you can't select which bit to download, your only option it to get the lot and then throw away what you don't want. If you want to use lossless data compression, the best place to use it would be in the BitTorrent client when they do piece exchange? > > > The reason why we would like to Tar the files together is because of things > like subtitles, artwork, cuts of music, other metadata pieces, etc. We're > not just talking a collection of video files.
