#237 in Compression
75KB
2K
SLoC
LZO1X
Safe Rust port of the LZO1X compression algorithm.
All functionality has been completely cross-tested against the original C implementation using lzo-sys.
Performance
Decompression
Below are decompression benchmarks of files found in the Calgary Corpus. The performance is compared to the original lzo1x_decompress_safe decompressor using lzo-sys. The benchmark times are given in nanoseconds, and the compression level used was 3. The benchmarks were run on Windows 11 using an AMD Ryzen 7 3700X processor.

Compression
Compression is in general significantly slower than decompression, and also slower when compared to the original C implementations using lzo-sys.
