My parallel archiver is using Parallel Zlib so it's fast, so since Parrallel Zlib is fast , the P (parallel part) of the Amdahl equation is much smaller than with Parallel Bzip, so since it's using a lot the memory and the harddisk also, it gives 2.5x speed with 4 threads on 4 cores. And thats not so bad since we are speeding up the things 2.5x times, ParallelBzip is mush slower, so the P part is much bigger than with Parallel Zlib , and it gives over 3.4x speed with Parallel Bzip. Thank's, Amine Moulay Ramdane.
