1. 源：
2. 安装：
注意在编译时,可以先把对应的libmysqlclient.so.*拷贝到/usr/lib
3. 测试：
[root@DB_Backup smacks]# super-smack -d mysql select-key.smack 10 10000
Query Barrel Report for client smacker1
connect: max=37ms min=0ms avg= 10ms from 10 clients
Query_type num_queries max_time min_time q_per_s
select_index 200000 0 0 10148.47
[root@DB_Backup smacks]# super-smack -d mysql update-select.smack 10 1000
Query Barrel Report for client smacker
connect: max=2ms min=0ms avg= 0ms from 10 clients
Query_type num_queries max_time min_time q_per_s
select_index 10000 1 0 4038.90
update_index 10000 1 0 4038.90
在以上测试结果中，
* 10代表10个客户端同时接入，1000代表每个客户端的查询次数（脚本中，对查询次数做了翻倍处理）
* max、min、avg为客户端最大、最小、平均连接时间
* num_queries、max_time、min_time为总请求次数，最大、最小查询时间（以毫秒为单位）
* q_per_s为每秒处理的请求数
4. 错误处理
