Revision as of 19:46, 21 April 2018
Comparison
All tests were performed using lzbench 1.7.3 (64-bit Linux), default compile options, gcc 7.3.0.
All lzbench runs were performed twice in a row, the second run is recorded here. Only 1 core is used by all algorithms in this test set (though some of them are multi-threading capable).
Hardware: Laptop, AMD A10-8700P (4 cores, 1.8MHz); all 4 cores set to "performance" cpufreq governor; 8GB RAM
All results should be taken with a grain of salt, this is not a very scientific setup; speeds can vary quite a bit with each run as well, and the results can depend on quite a lot of things and will vary for other systems, other data, etc. etc.
