This page shows how miniz.c v1.10 compares to several other popular open source data compression codecs at compression level 9 (max compression), with two examples at level 1 (fastest compression) on enwik8 and enwik9. The data here was generated using a slightly modified and enhanced version of [http://en.wikipedia.org/wiki/John_W._Ratcliff John Ratcliff's] [http://code.google.com/p/compressiontest/ compressiontest] project, compiled to x64.
This page shows how miniz.c v1.10 compares to several other popular open source lossless data compression codecs at compression level 9 (max compression), with two examples at level 1 (fastest compression) on enwik8 and enwik9. The data here was generated using a slightly modified and enhanced version of [http://en.wikipedia.org/wiki/John_W._Ratcliff John Ratcliff's] [http://code.google.com/p/compressiontest/ compressiontest] project, compiled to x64.
miniz.c's typical decompression rate is around 175-250 MB/sec. on a Core i7, and its typical compression rate is anywhere from 7-120.5MB/s (actual rates depend on the compression level, as well as the compressibility and redundancy present in the source data). The x64 version of the decompressor is faster than the x86 version, sometimes up to 20%, mostly due to good register utilization. miniz.c's inflater can be optionally configured to use a 64-bit bitbuffer on 64-bit CPU's, and unaligned 16 and 32-bit loads on little endian platforms (the tests below had both optimizations enabled).
