Merhaba

sysbench çıktısındaki bir veri hakkında bilgi bulamadım.

pi@raspberry ~ $ sysbench --test=cpu --cpu-max-prime=20000 --max-time=60
--num-threads=4 run

sysbench 0.4.12:  multi-threaded system evaluation benchmark



Running the test with following options:

Number of threads: 4



Doing CPU performance benchmark



Threads started!

Time limit exceeded, exiting...

(last message repeated 3 times)

Done.



Maximum prime number checked in CPU test: 20000





Test execution summary:

    total time:                          60.0556s

    total number of events:              2823

    total time taken by event execution: 240.1588

    per-request statistics:

         min:                                 83.01ms

         avg:                                 85.07ms

         max:                                140.74ms

         approx.  95 percentile:              87.66ms



Threads fairness:

    events (avg/stddev):           705.7500/1.92

    execution time (avg/stddev):   60.0397/0.02


Çıktının son iki satırındaki stddev (1.92, 0.02) değerlerinin ne olduğu ve
nasıl yorumlanması gerektiği hakkında bilgisi olan var mı?

Teşekkürler.
