IGZIP is a fast compression library supporting the DEFLATE and GZIP formats. It is much faster than the standard “gzip -1”, although its compression ratio is slightly worse. It can be built in two different variants that trade-off compression ratio for speed. It can be built under Linux* or Windows*.
This version includes optional optimizations that improve the compression ratio of genomic SAM and BAM files to near “gzip -1” levels, while still maintaining a significant speed advantage.
