Comparison

Features

sak has some features not present in most decompressors (such as lzip or zstd)

  • transcode - converts from one compressed format to another (streaming)
  • recompress - loads a file into memory and compresses it at a higher level
  • verify - simply verifies that a file is valid
Performance

Performance should be on the same order of magnitude as the various C command-line tools (gzip, lzop, zstd, &c.).
