为了验证MariaDB官网压测结果，特找了三台低配物理机做压测
https://mariadb.org/maria-10-1-mysql-5-7-commodity-hardware/
192.168.143.244 sysbench 192.168.143.245 MySQL 5.7.17 192.168.143.246 MariaDB 10.1.19 Enterprise
工具sysbench0.5 128并发 10张表100万行
硬件配置R720 64G RAID10(SAS 15000转)
分别压测30分钟
sysbench --test=/root/soft/sysbench-0.5/sysbench/tests/db/oltp.lua --mysql-table-engine=innodb --oltp-table-size=1000000 --max-requests=0 --max-time=1800 --num-threads=128 --oltp-tables-count=10 --report-interval=10 --mysql-host=192.168.143.245 --mysql-port=3306 --mysql-user=admin --mysql-password=123456 --mysql-db=test run
压测参数-参考官网：

192.168.143.245（MySQL 5.7.17，Buffer_Pool_Size为30G）
压测结果
--------------------------------------------------
192.168.143.246（MariaDB 10.1.19 Enterprise，Buffer_Pool_Size为30G，未开启Thread Pool线程池）
压测结果
-------------------------------------------------
总结
在QPS相同的情况下，MariaDB 10.1.19 Enterprise在CPU负载上利用率更低，基本符合MariaDB官网的压测结果。
