楼主

最近写了个java的程序来测试mysql 与mongodb的性能，代码如下：

package mongotest;
import com.mongodb.Mongo;
import com.mongodb.DB;
import com.mongodb.DBCollection;
import com.mongodb.BasicDBObject;
import com.mongodb.DBObject;
import com.mongodb.MongoException;
import java.net.UnknownHostException;
import java.sql.*;

mysql为innodb,数据库表结构如下：

CREATE TABLE IF NOT EXISTS `test` (
`id` int(11) NOT NULL auto_increment,
`count` int(11) NOT NULL default '0',
`test1` varchar(256) NOT NULL,
`test2` varchar(256) NOT NULL,
`test3` varchar(256) NOT NULL,
`test4` varchar(256) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ;

测试是在两台虚拟机之间进行，两台虚拟机在同一台exsi的物理机上，所以中间的网络延时基本为0。每行数据大小为1k。

测试结果：

1) mysql 插入50万行数据

[root@web dist]# java -jar "mongotest.jar" mysql insert 500000
Total run time:545 sec
Total rows:500000
mysql insert Result:917row/sec

资源占用：

Cpu(s): 7.4%us, 4.7%sy, 0.0%ni, 11.7%id, 72.6%wa, 0.7%hi, 3.0%si, 0.0%st?? load average为1以下

2）mysql更新50万行数据

[root@web dist]# java -jar "mongotest.jar" mysql update 500000
Total run time:838 sec
Total rows:500000
mysql update Result:596row/sec

资源占用：

Cpu(s): 7.4%us, 3.3%sy, 0.0%ni, 6.7%id, 80.6%wa, 0.7%hi, 1.3%si, 0.0%st???? load average为1以下

3) mongo插入50万行数据

[root@web dist]# java -jar "mongotest.jar" mongo insert 500000????
Total run time:52 sec
Total rows:500000
mongo insert Result:9615row/sec

把数据清空，第二次跑测试程序，速度要慢一些。

[root@web dist]# java -jar "mongotest.jar" mongo insert 500000
Total run time:60 sec
Total rows:500000
mongo insert Result:8333row/sec

资源占用：

Cpu(s): 6.0%us, 3.0%sy, 0.0%ni, 0.0%id, 88.6%wa, 0.3%hi, 2.0%si, 0.0%st load average为1.5~2.0

4) mongo更新50万行数据

[root@web dist]# java -jar "mongotest.jar" mongo update 500000
Total run time:32 sec
Total rows:500000
mongo update Result:15625row/sec

资源占用：

Cpu(s): 90.0%us, 7.4%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 2.7%si, 0.0%st???? load average为1以下

5) mysql 插入100万行数据

[root@web dist]# java -jar "mongotest.jar" mysql insert 1000000
Total run time:1085 sec
Total rows:1000000
mysql insert Result:921row/sec

资源占用和50万差不多。

6) mysql 更新100万行数据

[root@web dist]# java -jar "mongotest.jar" mysql update 1000000
Total run time:1646 sec
Total rows:1000000
mysql update Result:607row/sec

资源占用和50万差不多。

7) mongo插入100万行数据

[root@web dist]# java -jar "mongotest.jar" mongo insert 1000000???
Total run time:120 sec
Total rows:1000000
mongo insert Result:8333row/sec

资源占用明显增高了很多，系统基本不能操作了。
