Lzo2

Portable speedy, lossless data compression library

LZO is a data compression library which is suitable for data de-/compression in real-time. This means it favours speed over compression ratio.

LZO implements a number of algorithms with the following features

• Decompression is simple and very fast.
• Requires no memory for decompression.
• Compression is pretty fast.
• Requires 64 kB of memory for compression.
• Allows you to dial up extra compression at a speed cost in the compressor. The speed of the decompressor is not reduced.
• Includes compression levels for generating pre-compressed data which achieve a quite competitive compression ratio.
• There is also a compression level which needs only 8 kB for compression.
• Algorithm is thread safe.
• Algorithm is lossless.
