Special Parameters

The LZO coding initialization functions have a special parameter method. This parameter specifies level of parallelization and generic LZO compatibility to be used in the LZO encoding. The table below lists possible values of the method parameter and their meanings.

Parameter method for the LZO Compression Functions
Value Descriptions
IppLZO1XST

The compression and decompression are performed sequentially in a single-thread mode with full binary compatibility with generic LZO libraries and applications.

IppLZO1XMT

The compression and decompression are performed in parallel (multi-threaded mode), it is more fast, but not compatible with the generic LZO.

IppLZO1X1ST

The compression and decompression are performed sequentially in a single-threaded mode with full binary compatibility with generic LZO libraries and applications.

The compression ratio of this method corresponds to the LZO lzo1x_1_compress function (default function for the lzop compressor). The IppLZO1X1ST method provides lower compression ratio than IppLZO1XST but better compression performance.
