zlib

(Z LIBrary) A set of compression/decompression routines written by Jean-loup Gailly and Mark Adler that is widely used in Linux and Unix operating systems. Zlib is open source and royalty-free software, and unlike the LZW compression algorithm, zlib does not increase the file size. For more information, visit www.gzip.org/zlib.

Without compression, there is not much difference between a text file and RCFile, but ORCFile can decrease the file size significantly compare with other file formats because ORCFile uses a default compression technique (ZLIB).
Google further explains in its blog that the output generated by Zopfli is about 3-8 percent smaller as compared to zlib at the maximum compression.
"Due to the amount of CPU time required - 2 to 3 orders of magnitude more than zlib at maximum quality - Zopfli is best suited for applications where data is compressed once and sent over a network many times, for example, static content for the web.
Streamed uncompression is possible for deflate encoding, implemented by zlib [12] and used by Adobe [13].
"Furthermore, the vulnerable JavaScript is obfuscated inside a 'zlib' stream making universal detection and intrusion detection signatures much more difficult." <p>Moore, the creator of Metasploit and chief security officer for security company Rapid7, echoed Shadowserver's advice.
Each page is compressed using zlib. The choice of compression technique is a tradeoff between speed and compression ratio.
FSP optionally supports on-the-fly per-block compression using the library zlib (12) with configurable compression levels.
The goal of the study was to parallelize the ZLIB compression library for the cell broadband engine.
Box2D is a popular 2D physics engine library which is open source and disributed under the permissive zlib license.
The video encoding format chosen is Screen video, which uses the zlib compression for the frames.
Due to performance reasons, in this library, we include new and high level functionalities (queries) which leverage the GridFTP protocol [10], compression technique (zlib [11]) and translation mechanism from XML to SQL.
