mysql压力测试工具.doc

Super-smack 是一个强大的广受赞誉的压力测试工具，支持MySQL和PostgreSQL。这个工具程序现在由 Tony Bourke 维护。安装Super-smack 现在是1.3版，源码下载地址如下：/tony/supersmack/super-smack-1.3.tar.gz./configurewith-mysqlwith-pgsql根据需要，可以只保留 MySQL 和 PostgreSQL 中的一个。如果你的 client library 安装在其他目录，你要指明它，例如：./configurewith-mysql=/opt/mysql然后makesumake installPS. FreeBSD 下面有 ports 的，安装起来更方便。使用将程序提供的 smack 样本文件重新拷贝一份，然后编辑此文件，填入相应的连接信息，比如用户名、密码、端口和测试所用的数据库名。cp /usr/share/smacks/select-key.smack select-key-mysql.smack开始运行super-smack d mysql select-key-mysql.smack 10 100010 是连接客户的数目，每个客户有100次轮询。结果Query Barrel Report for client smacker1connect: max=66ms min=0ms avg= 66ms from 10 clientsQuerytype numqueries maxtime mintime qpersselect_index 20000 0 0 4360.61这表示 super-smack 运行了10个客户，客户连接最长时间为66毫秒，最短的则没有延迟，平均时间为62毫秒。Super-smack 总共执行了20000此查询，每个查询所花时间都小于1毫秒。整个测试期间，服务端平均每秒执行了4360.61次 select_index 型查询。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。另外，可以修改 smack文件中 相应的参数以符合你的测试要求。Files:/usr/local/bin/gen-data/usr/local/bin/super-smack/usr/local/share/super-smack/select-key.smack/usr/local/share/super-smack/update-select.smack1. 源：/tony/supersmack/2. 安装：注意在编译时,可以先把对应的libmysqlclient.so.*拷贝到/usr/lib3. 测试：rootDB_Backup smacks# super-smack -d mysql select-key.smack 10 10000Query Barrel Report for client smacker1connect: max=37ms min=0ms avg= 10ms from 10 clientsQuery_type num_queries max_time min_time q_per_sselect_index 200000 0 0 10148.47rootDB_Backup smacks# super-smack -d mysql update-select.smack 10 1000Query Barrel Report for client smackerconnect: max=2ms min=0ms avg= 0ms from 10 clientsQuery_type num_queries max_time min_time q_per_sselect_index 10000 1 0 4038.90update_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=1.下载软件 /tony/supersmack/ 2.编译安装 ./configure -prefix=/usr/local/supersmack -with-mysql -with-mysql-lib=/usr/local/mysql/lib/mysql/ -with-mysql-include=/usr/local/mysql/include/mysql/ 注意红色字体代表的目录，并不是默认的mysql/lib和mysql/include rootmysql super-smack-1.3# makerootmysql super-smack-1.3# make install 3.配置测试信息rootmysql bin# cp /usr/share/smacks/select-key.smack /usr/local/supersmack/bin/rootmysql bin# cp /usr/local/supersmack/bin/* /usr/bin/ 修改select-key.smack 里面的帐号密码及测试使用的数据库。4.开始测试 测试myiasm引擎 select-key性能rootmysql bin# super-smack -d mysql select-key.smack 10 1000./super-smack: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory 缺少库文件，将该文件CP到系统目录下# cp /usr/local/mysql/lib/mysql/libmysqlclient.so.16 /usr/lib 如果无法载入数据，则按以下方法处理/usr/local/supersmack/bin/gen-data -n 90000 -f %12-12s%n,%25-25s,%n,%d/var/smack-data/words.dat 再次运行测试rootmysql bin# ./super-smack -d mysql select-key.smack 100 200Query Barrel Report for client smacker1connect: max=391ms min=1ms avg= 51ms from 100 clients Query_type num_queries max_time min_time q_per_sselect_index 40000 0 0 3713.30 100用户执行200次轮询，共执行40000次查询update-select性能rootmysql bin# ./super-smack -d mysql update-select.smack 100 200Query Barrel Report for client smackerconnect: max=2300ms min=1ms avg= 70ms from 100 clients Query_type num_queries max_time min_time q_per_sselect_index 20000 18 0 1428.06update_index 20000 20 0 1428.06 innodb测试mysql alter table http_auth engine=innodb;Query OK, 90000 rows affected (1.85 sec)Records: 90000 Duplicates: 0 Warnings: 0 select-keyrootmysql bin# ./super-smack -d mysql select-key.smack 100 200Query Barrel Report for client smacker1connect: max=683ms min=1ms avg= 59ms from 100 clients Query_type num_queries max_time min_time q_per_sselect_index 40000 0 0 3694.71update-selectrootmysql bin# ./super-smack -d mysql update-select.smack 100 200Que
