Compression Benchmark

[Yann]

Objective of this thread is to compare fast compression algorithms, estimating their speed/rate relative performances.
We are interested in algorithm efficiency, effectively measuring its single-core performance to represent its energy effectiveness. An algorithm which uses several cores will simply see its total time representing the sum of each core usage.
The final result is a graphic chart per file type.

Method :
Test system is a Core 2 Duo 8400 @3GHz, with 2GB RAM DDR2-800, using Windows Seven OS.
Timing is measured using timer v8.0, from Igor Pavlov.
Files are processed 5 times, median value is used.
Process time (kernel time + user time) is considered. Therefore, it excludes disk I/O time. Note however that kernel time, which represents the energy required by OS to manage the compression algorithm, can take a significant portion of overall time for fast algorithms.

Compression benchmark on binary file

This is a public benchmark. You can ask for a specific compressor to be present in the list.

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 : win98.vmdk vmware virtual hdd content (328 073 216 Bytes) (not downloadable).
