Benchmark du RaspberryPI
Voici quelques test effectués sur mon RaspberryPI, les résultats sont fait sans overcloking
Pour effectuer les tests:
Récupération du programme de Test: merci à http://www.syris.fr/
wget http://byte-unixbench.googlecode.com/files/UnixBench5.1.3.tgz
tar xvzf UnixBench5.1.3.tgz
cd UnixBench/
./Run
éventuellement il faut installer gcc: apt-get install gcc
