使用sysbench对Oracle做基准测试(四) MUTEX

--num-threads  --进程的数量
--mutex-num    --mutex的数量
--mutex-locks  --每次请求的mutex lock的数量
--mutex-loops  --申请lock之前执行ok那个循环的次数
[root@localhost sysbench]# ./sysbench --test=mutex --num-threads=12 --mutex-num=10240  --mutex-locks=1000000 --mutex-loops=50000000 run
sysbench 0.5:  multi-threaded system evaluation benchmark

Running the test with following options:
Number of threads: 12
Random number generator seed is 0 and will be ignored
