來一個使用sysbench測試cpu性能的簡單腳本

#!/bin/bash

for ((i=1; i<16; i++)); do
    sysbench cpu run --cpu-max-prime=10000 --threads=4 --time=60 > ${i}.sysbench
done

sb_result=sysbench_result
touch ${sb_result}
for ((i=1; i<16; i++)); do
    cat ${i}.sysbench |grep second|awk -F ':' '{print $2}'|sed 's/ //g' >>${sb_result}
done

　　

這裏，計算10000以內的素數，使用4個線程cpu，運行時間60秒，連續運行16次。我只取了每秒處理event的數量做爲對比。

每次完整輸出以下：

sysbench 1.0.9 (using system LuaJIT 2.0.4)

Running the test with following options:
Number of threads: 4
Initializing random number generator from current time


Prime numbers limit: 10000

Initializing worker threads...
