LKBEN11696: How to check CPU speed with sysbench on a linux system.

Symptom

You would like to know which system is faster.

Cause

Solution

A fast and easy cpu performance check between two systems can be done with sysbench.

A nice test for the cpu is to compare with the following command:

sysbench cpu --cpu-max-prime=20000 --threads=8 --time=0 --events=10000 run

Check the time the system needed to execute the command.

e.g. on an older SuperMicro Server this command took about 4,57 seconds. On an AMD 5600G the same command took only 0,8120 seconds.

Number of threads: 8
Initializing random number generator from current time


Prime numbers limit: 20000

Initializing worker threads...

Threads started!

CPU speed:
    events per second: 12309.00

General statistics:
    total time:                          0.8120s
    total number of events:              10000

Latency (ms):
         min:                                    0.50
         avg:                                    0.65
         max:                                    1.05
         95th percentile:                        0.92
         sum:                                 6491.76

Threads fairness:
    events (avg/stddev):           1250.0000/364.00
    execution time (avg/stddev):   0.8115/0.00

Have fun.
