Subject: Linux Kernel Source Compression
Date: Sun, 21 May 2006 10:35:00 -0400 (EDT) [thread overview]
Message-ID: <Pine.LNX.4.64.0605211028100.4037@p34> (raw)
Was curious as to which utilities would offer the best compression ratio
for the kernel source, I thought it'd be bzip2 or rar but lzma wins,
roughly 6 MiB smaller than bzip2.
