个人简介

博客很久没有更新了,原因是大多数时间都忙在研究技术上,却懒得腾时间出来把技术分享,最近在开源力量上开课《Mongodb管理与维护》,让屌丝们从0到精通,敬请关注。本博客技术原创更新滞后一些,找时间更新有关mysql,mongodb等内容,谢谢大家关注。

mysqlslap工具使用





工具运行分为4个步骤:
创建数据库和表
插入数据
执行查询更新 等操作 query(测试的主要内容)以下称为查询
删除数据库

1.使用自动生成的脚本测试
mysqlslap --help可以查看具体的参数的用法

例子:mysqlslap --concurrency=50,100,200 --iterations=20 --number-int-cols=4 --number-char-cols=35 --auto-generate-sql --auto-generate-sql-add-autoincrement --auto-generate-sql-load-type=read --engine=myisam,innodb --number-of-queries=200 --verbose --socket=/usr/local/mysql1/var/mysql.sock -u root -p123
使用系统自带的脚本测试,增 加auto_increment一列,int4列char35列,测试2种引擎myisam,innodb读的性能分别用50,100,200个客户端对 服务器进行测试总共200个查询语句 执行20次查询
加个--only-print不连接数据库只打印要做什么    

Benchmark
        Running for engine myisam
        Average number of seconds to run all queries: 0.897 seconds
        Minimum number of seconds to run all queries: 0.081 seconds
        Maximum number of seconds to run all queries: 1.239 seconds
        Number of clients running queries: 50
        Average number of queries per client: 4
###### 50个并发客户端 平均每个客户端4个查询 20次查询中最少的时间是0.081秒、 最多1.239秒、平均0.897秒。

--host
--password
--pipe
--port
--protocol
--socket
--user
这 些参数都是连接参数使用
--post-query=value

测试完成以后执行的SQL语句的文件或者字符串 这个过程不影响时间计算

--post-system=str

输出更多的信 息

更多的参数可以参考http://dev.mysql.com/doc/refman/5.1/en /mysqlslap.html#option_mysqlslap_number-of-queries


总结:经过测试得出如 下结论
对于工具评价:工具可以模拟多个客户端同时并发的向服务器发出查询更新,给出了性能测试数据。而且提供了多种引擎的比较。
不过我对 有些数据为0值得怀疑
