====== Faire un benchmark de son système linux ======

Il existe plusieurs outils mais [[http://www.howtoforge.com/how-to-benchmark-your-system-cpu-file-io-mysql-with-sysbench|celui-ci]] me semblait le plus simple et utilisable.

Sur un ubuntu :

<code bash>
sudo apt-get install sysbench
</code>

Par exemple pour bencher un CPU :

<code bash>
sysbench --test=cpu --cpu-max-prime=20000 run
</code>

Ce qui donne ce genre de chose :

<code>
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
