1、安装supersmack
http://vegan.net/tony/supersmack/
安装过程以及我中间遇到问题的总结都在这里。

之前记得把libmysqlclient.so.16拷贝到/usr/lib中去，这样make 的时候不用改MakeFile文件。
[root@localhost super-smack-1.3]# cp /usr/local/mysql/libmysqlclient.so.16 /usr/lib

我遇到的问题如下：
error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory
看到北京野狼的这个帖子：
http://bbs.chinaunix.net/archiver/?tid-638662.html

[root@localhost super-smack-1.2]# ./configure –with-mysql
configure: error: installation or configuration problem: C++ compiler cannot create executables.
没有安装C++编译器

If this is not what you intended, please re-run configure.

Thanks for using super-smack!
然后make;make install

2、进行实际测试。
拷贝示例文件。
[root@localhost super-smack-1.3]# cp -r smacks/ /usr/local/bin/
修改用户名和密码为自己的

默认是测试MYISAM表的性能。

[root@localhost smacks]# super-smack -d mysql select-key.smack 10 1000
Error running query select count(*) from http_auth:Table ‘test.http_auth’ doesn’t exist
Creating table ‘http_auth’
Loading data from file ‘/var/smack-data/words.dat’ into table ‘http_auth’
Table http_auth is now ready for the test
Query Barrel Report for client smacker1
connect: max=156ms  min=0ms avg= 21ms from 10 clients
Query_type      num_queries     max_time        min_time        q_per_s
select_index    20000   0       0       16299.96

10 是连接客户的数目，每个客户有100次轮询。
结果表示：super-smack总共执行了2W次查询，每秒执行16299.96 条数据

下来测试innodb 表
进入MYSQL的SHELL，修改表类型
mysql> alter table http_auth engine innodb;
Query OK, 90000 rows affected (15.18 sec)
Records: 90000  Duplicates: 0  Warnings: 0

[root@localhost smacks]# super-smack -d mysql select-key.smack 10 1000
Query Barrel Report for client smacker1
connect: max=117ms  min=0ms avg= 18ms from 10 clients
Query_type      num_queries     max_time        min_time        q_per_s
select_index    20000   0       0       16747.00
[root@localhost smacks]#
接下来测试集群的

mysql> alter table http_auth engine ndb;
Query OK, 90000 rows affected (11.14 sec)
Records: 90000  Duplicates: 0  Warnings: 0

[root@localhost smacks]# super-smack -d mysql select-key.smack 10 1000
Query Barrel Report for client smacker1
connect: max=3ms  min=0ms avg= 0ms from 10 clients
Query_type      num_queries     max_time        min_time        q_per_s
select_index    20000   3       1       2587.91

看一下update的。
[root@localhost smacks]# super-smack -d mysql update-select.smack 100 10000
Table ‘http_auth’ does not meet condtions, will be dropped
Creating table ‘http_auth’
Loading data from file ‘/var/smack-data/words.dat’ into table ‘http_auth’
Table http_auth is now ready for the test
Query Barrel Report for client smacker
connect: max=752ms  min=0ms avg= 108ms from 100 clients
Query_type      num_queries     max_time        min_time        q_per_s
select_index    1000000 19      0       3837.48
update_index    1000000 20      0       3837.48

这个测试结果怎么表名MYISAM表的SELECT比INNODB的还差。
具体原因我会找找看。
