The idea of this place is to compare the compressors present in this forum with each other.

Compression benchmark on text files

Compression benchmark on binary file

Method :
Timing is measured using timer v8.0, from Igor Pavlov, of 7zip.
File is processed 5 times, and the "Process Time" median value is used (including kernel, but excluding hdd).
Test system is a Core 2 Duo 8400 @3GHz, with 2GB of RAM, using Windows Seven OS.

Test File : enwik8 , from LTCB . (100 000 000 Bytes).


Note : the blue line represent better speed/ratio
