4.2 测试环境
- Dell PowerEdge R410
- RAM：64G
- Kernel: 2.6.32
- MongoDB：3.0.7
- MySQL：5.5.40
- Linux OS：CentOS release 6.5 x86_64
- CPU：Intel(R) Xeon(R) CPU X5650 @2.67GHz / 24 cores
4.3 测试过程
测试的数据量变量名假定为size,分别取值为200w、400w、600w、800w、1000w.
每次使用单进程对单个表压测,每个表均含有4个字段,每次压测时间不超过30分钟.
为了让数据更加符合我们想要的结果,每轮测试完成后,我们都重启mysqld和mongodb实例,并且用下面的方法删除系统cache,释放swap.
#sync — 将脏数据刷新到磁盘
#echo 3 > /proc/sys/vm/drop_caches — 清除OS Cache
#swapoff -a && swapon -a
4.3.1 sysbench
4.3.1.1 准备工作
(1) 创建测试库
mysql> drop database if exists sysbench_test;
mysql> create database if not exists sysbench_test character set utf8 collate utf8_general_ci;
(2) 查看表结构
`id` int(10) unsigned NOT NULL auto_increment,
`k` int(10) unsigned NOT NULL default ‘0’,
`c` char(120) NOT NULL default ”,
`pad` char(60) NOT NULL default ”,
PRIMARY KEY (`id`),
KEY `k` (`k`));
