三、sysbench使用
1、CPU性能測試
cpu性能測試：找范圍內(nèi)大素數(shù){時間越短越好}
cpu性能測試主要是根據(jù)素數(shù)的加法運算，這里指定大素數(shù)(質(zhì)數(shù))為80000，--num-threads=`grep "processor" /proc/cpuinfo | wc -l`指定線程數(shù)，默認是1
/usr/local/sysbench/bin/sysbench --test=cpu --cpu-max-prime=80000 run

[root@db_test ~]# /usr/local/sysbench/bin/sysbench --test=cpu --cpu-max-prime=80000 run
WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.
sysbench 1.0.3 (using bundled LuaJIT 2.1.0-beta2)
Running the test with following options:
Number of threads: 1
Initializing random number generator from current time
Prime numbers limit: 80000
Initializing worker threads...
Threads started!
General statistics:
total time: 10.0057s
total number of events: 520
Latency (ms):
min: 18.74
avg: 19.24
max: 19.39
95th percentile: 19.29
sum: 10005.32
Threads fairness:
events (avg/stddev): 520.0000/0.00
execution time (avg/stddev): 10.0053/0.00
實際環(huán)境CPU拷機壓測腳本如下：
echo -e "進行CPU壓力測試: 尋找小于1千萬的大質(zhì)數(shù),并發(fā)線程數(shù)10,大請求數(shù)100 "
/usr/local/bin/sysbench --num-threads=10 --max-requests=100 --test=cpu --debug --cpu-max-prime=10000000 run
2、內(nèi)存性能測試
sysbench 測試memory的時候是順序讀或?qū)憙?nèi)存的。根據(jù)選項的不同，每次操作過程中，每個線程可以獲取global或本地的數(shù)據(jù)塊
內(nèi)存：以不同塊大小傳輸一定數(shù)量的數(shù)據(jù)吞吐量大小{越大越好}

WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.
sysbench 1.0.3 (using bundled LuaJIT 2.1.0-beta2)
memory options:
