看到又推出新"舊"系列 (Azure A3 and A4v2 Benchmark)

來試下(結果是並無差別…)

使用sysbench

Azure A3 std

root@wantgooM:~# sysbench --test=cpu --cpu-max-prime=20000 --num-threads=4 run -> default cpu-max-prime=10000 and default num-threads=1
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!
Done.

Maximum prime number checked in CPU test: 20000


Test execution summary:
    total time:                          19.2541s
    total number of events:              10000
    total time taken by event execution: 76.9445
    per-request statistics:
         min:                                  2.58ms
         avg:                                  7.69ms
         max:                                 67.12ms
         approx.  95 percentile:               9.71ms

Threads fairness:
    events (avg/stddev):           2500.0000/105.02
    execution time (avg/stddev):   19.2361/0.01
