PeaZip maximum compression benchmark
2020-06-17 01:45 (by giorgio_tani)

New PeaZip compression benchmark, comparing 7Z, ARC, RAR, ZIPX, and ZPAQ for compression ratio and compression / decompression speed.

Each format is tested at minimum, default, and maximum compression level, with default compression algorithm and default compression settings. Input data is composed by enwik8, and Calgary, Canterbury, and Silesia corpora.

Goals of the maximum compression benchmark are:

1) discover what format provides best compression ratio

2) understand how compression ratio and performances varies, for each format, from minimum to maximum compression level
