MySQL 压力测试工具super smack

1. 源:http://vegan.net/tony/supersmack/

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
