Il existe plusieurs outils mais celui-ci me semblait le plus simple et utilisable.
Sur un ubuntu :
sudo apt-get install sysbench
Par exemple pour bencher un CPU :
sysbench --test=cpu --cpu-max-prime=20000 run
Ce qui donne ce genre de chose :
sysbench 0.4.12: multi-threaded system evaluation benchmark
Running the test with following options:
Number of threads: 1
Doing CPU performance benchmark
Threads started!
Done.
Maximum prime number checked in CPU test: 20000
Test execution summary:
total time: 25.0056s
total number of events: 10000
total time taken by event execution: 24.9996
per-request statistics:
min: 2.47ms
avg: 2.50ms
max: 37.23ms
approx. 95 percentile: 2.50ms
Threads fairness:
events (avg/stddev): 10000.0000/0.00
execution time (avg/stddev): 24.9996/0.00
