Subdirectories, and re-zip it (though this time I used the defaultĬompression level rather than maximum, and specified lzma2). The compressed file, restructure the directory with 4096 Of slowing down over time was happening regardless of which I wasįollowing advice in the comments, I used my Windows machine to unzip Installation, perhaps b/c I set it up as a raid array). Ntfs (I think I remember this being recommended by Ubuntu during Installation that is ext4 (my ssd), though I have another one that is I should clarify that I actually have one drive on my main Ubuntu My main computer uses ext4 file system, and the version of 7-Zip I have is 9.20:ħ-Zip 9.20 p7zip Version 9.20 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,12 CPUs) Any help would be tremendously appreciated. My sense is this has to do with something I don't know about Ubuntu (I'm a recovering Windows user) or my file system rather than 7-Zip. Obviously I can't have an extraction take several days, nor should I.
It also clearly made use of multiple processors, which I can't get 7-Zip to do on Ubuntu. However, on my Windows machine (Intel® Xeon® CPU E5-2687W 3.10GHz 3.10 GHz, which is only a slightly better machine, I extracted the entire directory in 15-20 minutes. Every time I try to extract, it starts off at disappointing, but acceptable speed, but slows down to a crawl as it gets further along (ran overnight and when I woke up it was doing about 300 files per minute). I then downloaded it to my main computer (Ubuntu, Intel® Xeon® CPU E5-1650 v2 3.50GHz). It took around 5-6 hours to compress (seems excessive).
I compressed it with 7-Zip using this command: 7z a -mx=9 Pages.7z Pages I have a directory called Pages of 2.2 million HTML files (about 80 GB) on an Ubuntu server.
