MYSQL-mysqlslap
简介：
mysqlslap is a diagnostic program designed to emulate client load for a MySQL server and to report the timing of each stage. It works as if multiple clients are accessing the server. mysqlslap is available as of MySQL 5.1.4.
官方文档语法：http://dev.mysql.com/doc/refman/5.1/en/mysqlslap.html
测试：
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqlslap --delimiter=";" --create="CREATE TABLE a (b int);INSERT INTO a VALUES (23)" --query="SELECT * FR
OM a" --concurrency=50 --iterations=200 -uroot -pw123123
Benchmark
Average number of seconds to run all queries: 0.133 seconds
Minimum number of seconds to run all queries: 0.046 seconds
Maximum number of seconds to run all queries: 1.219 seconds
Number of clients running queries: 50
Average number of queries per client: 1

mysql> select * from t1;
ERROR 1146 (42S02): Table 'mysqlslap.t1' doesn't exist
总结：从上述的实验中可以得出一个结论，测试时会创建数据库和插入数据并查询，完成测试后就好把整个测试数据库删除！！！
下边我们在做几个测试了解测试脚本是怎么写的：
1、仅仅打印执行脚本信息：
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqlslap.exe -a --only-print
DROP SCHEMA IF EXISTS `mysqlslap`;
CREATE SCHEMA `mysqlslap`;
use mysqlslap;
CREATE TABLE `t1` (intcol1 INT(32) ,charcol1 VARCHAR(128));
INSERT INTO t1 VALUES (41,'nagT4IIMk551R1Bv2RcrO2ZsMLwebn6BI9snJvuNr2ZZkLXtSnkMxxJNLpyGbqiomg24SQlq9Aq6LZ89NOacKmwBSOfQjHyei9hZbJIOWxQt6h5ksW9HZxCmWhcbnF');
。。。。。。。
DROP SCHEMA IF EXISTS `mysqlslap`;
C:\Program Files\MySQL\MySQL Server 5.5\bin>
可以清楚的看到执行语句和过程！！！！ 此时插入的数据是一列数字类型和一列字符类型的数据，要更改这个要用到几个参数：
–number-char-cols=N, -x N
自动生成的测试表中包含多少个字符类型的列，默认1
–number-int-cols=N, -y N
自动生成的测试表中包含多少个数字类型的列，默认1
了解了参数的意思之后，我们可以尽心一个小小的测试：
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqlslap.exe -a -y 2 -x 2 --only-print
拿出一条记录分析一下：
INSERT INTO t1 VALUES (6879,32301,'YckdqeC41gKjG17z8qsJez7O7dFDprMJchLu9ywTd4y25eYPcLfNnXt2KcoJ9tJXr3keC4fhatJupvM1GHYPXIqRvnkizLokuo1sSucdt1lIvus6GO6hkKuww75eXL','PrXJ0xcNkO5H2mb6sTml3Chmt4TqPm5qwvDj
CwwWGsWqvsAbGLgOTEq26GOqHMmGS5LWW21ZeEZF0yRKPNlctACTJNHpZzDgYP1ryjDRacHrpk6X2IMFnHyOMqmlgP');
可以很清楚的看到插入的数据是2列数字类型和2列字符类型的数据！
执行自己的sql语句：
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqlslap.exe -c 300 --create-schema=test --query="select * from userinfo" -uroot -pw123123
Benchmark
Average number of seconds to run all queries: 0.516 seconds
Minimum number of seconds to run all queries: 0.516 seconds
Maximum number of seconds to run all queries: 0.516 seconds
Number of clients running queries: 300
Average number of queries per client: 1
