For a C implementation, it could interesting to consider LZ4 algorithm, since it is written natively in this language. In contrast, Snappy has been ported to C by Andy from the original C++ Google code, which lso translate into less extensive usage and tests.
http://code.google.com/p/lz4/ Furthermode, LZ4 license is BSD. And it has been reported in several tests as being faster than Snappy/LZO, especially on decompression speed. http://article.gmane.org/gmane.comp.file-systems.btrfs/15744 And last point, there is a "high compression" mode, which could be useful for data rarely written/modified but often read. http://code.google.com/p/lz4hc/ -- View this message in context: http://postgresql.1045698.n5.nabble.com/Faster-compression-again-tp5565675p5615311.html Sent from the PostgreSQL - hackers mailing list archive at Nabble.com. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
