lzop是一个基于LZO压缩库的压缩软件。LZO是一个超级强大的压缩库，最大的特点就是压缩/解压速度极快，LZO 除了极快的压缩和解压速度以外，最重要的特性就是“就地解压”，即不使用临时文件，这对于体积较大的文件来说，例如光盘映像，是非常合适的。
另外解压无需内存，解压速度与压缩率无关，这两个也是特别棒的特性，相比较小的压缩率(现在随着大硬盘的普及，压缩率与压缩时间相比，前者显得不再那么重要了)，速度上的提高带来的优势无疑太很大了。应该是目前所有压缩软件中将压缩率、时间、内存用量关系处理地最好的软件了。
lzop is a file compressor which is very similar to gzip. lzop uses the LZO data compression library for compression services, and its main advantages over gzip are much higher compression and decompression speed (at the cost of some compression ratio).
lzop is copyrighted OpenSource software distributed under the terms of the GNU General Public License (GPL).
Features
lzop is the fastest compressor and decompressor around. See the well-known Archive Comparison Test for details.
On modern systems, when making backups of terrabyte of data, lzop is usually IO-bound and not CPU-bound, which means that you can both decrease storage requirements and effectively reduce backup time by quite an amount.
lzop was designed with the following goals in mind:
speed (both compression and decompression)
reasonable drop-in compatibility to gzip
portability
General functionality and behaviour has been modelled very closely after gzip. The main differences between lzop and gzip are:
files compressed by lzop will have the suffix `.lzo'
lzop does not delete the input file(s) by default.
