为了验证MariaDB官网压测结果，特找了三台低配物理机做压测

192.168.143.244 sysbench192.168.143.245 MySQL 5.7.17192.168.143.246 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)

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。
