Highlights of the 4.20 final version release:

  1. Changes in RAR compression:

a) RAR general compression algorithm is optimized for better utilization of several processor cores. While some speed gain is possible even in single processor mode, best results are achieved in multi-core environment.
Speed gain depends on data type and average file size. Several cores are utilized more efficiently when compressing large files.

b) "Fastest" (-m1) compression mode also supports several processor cores now. In 4.11 it could use only single processor core.

c) RAR general decompression algorithm speed is slightly improved, though not to same extent as RAR compression. RAR decompression is not able to use several processor cores, so its performance does not depend on a number of cores.

  1. Changes in ZIP compression:

a) now ZIP compression supports several processor cores resulting in noticeably higher performance in multi-core environment. Single CPU ZIP compression is also faster than in 4.11;
