Pi vs UDOO quick CPU performance test

First install the software

apt-get install sysbench

then run on PI:

 sysbench --test=cpu --cpu-max-prime=2000 run

on UDOO:

 sysbench --test=cpu --num-threads=4 --cpu-max-prime=2000 run

UDOO output:

Maximum prime number checked in CPU test: 2000
Test execution summary:
 total time: 20.8079s
 total number of events: 10000
 total time taken by event execution: 166.2889
 per-request statistics:
 min: 8.18ms
 avg: 16.63ms

 approx. 95 percentile: 28.23ms
Threads fairness:
 events (avg/stddev): 1250.0000/6.71
 execution time (avg/stddev): 20.7861/0.03
