http://sysbench.sourceforge.net/index.html

使ってみました。↓
$ sysbench --test=cpu --cpu-max-prime=20000 run
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: 55.0874s
total number of events: 10000
total time taken by event execution: 55.0833
per-request statistics:
min: 5.48ms
avg: 5.51ms
max: 12.92ms
approx. 95 percentile: 5.52ms

Threads fairness:
events (avg/stddev): 10000.0000/0.00
execution time (avg/stddev): 55.0833/0.00
