Subject: random minor benchmark: Re: Copy 20 tarfiles: ext2 vs (reiser4, unixfile) vs (reiser4,cryptcompress)

Message-ID: <43D7CA7F.4010502@namesys.com> (raw)

Notice how CPU speed (and number of cpus) completely determines
compression performance.
cryptcompress refers to the reiser4 compression plugin, (unix file)
refers to the reiser4 non-compressing plugin.
