[Bug 346548] New: Use LZMA compression algorithm instead of GZip or BZip2
https://bugzilla.novell.com/show_bug.cgi?id=346548 Summary: Use LZMA compression algorithm instead of GZip or BZip2 Product: openSUSE 10.3 Version: Final Platform: All OS/Version: openSUSE 10.3 Status: NEW Severity: Enhancement Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: landemaine@gmail.com QAContact: qa@suse.de Found By: --- I found out that we can reduce file size by up to 30-35% if we use LZMA instead of GZip or BZip2. ISO images can be reduced to 500MiB, and updates on repositories can download faster. You need to install the 7-Zip application (p7zip) to be able to compress a file using LZMA, make sure you use the most aggressive options to reach the best compression rate. You can do the test and you'll be amazed, even if it takes more time to compress. You need to tar your files first, to keep user privileges, and then you zip the tar file: % 7z a -m0=lzma -mx=9 -mfb=64 -ms=on file.7z file.tar More info: http://www.7-zip.org -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This might significantly increase the amount of memory needed by the installer, thereby increasing the hardware requirements for the OS; this could easily be a deal-breaker.
yes, i think this is no no. better compression yes - but not pay for that with increased memory usage. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
