MySQLslap是一个MySQL官方提供的压力测试工具。以下是比较重要的参数:

–defaults-file,配置文件存放位置

–concurrency,并发数

–engines,引擎

–iterations,迭代的实验次数

–socket,socket文件位置

自动测试:

–auto-generate-sql,自动产生测试SQL

–auto-generate-sql-load-type,测试SQL的类型。类型有mixed,update,write,key,read。

–number-of-queries,执行的SQL总数量

–number-int-cols,表内int列的数量

–number-char-cols,表内char列的数量

例如:

shell>MySQLslap –defaults-file=/u01/MySQL1/MySQL/my.cnf –concurrency=50,100 –iterations=1 –number-int-cols=4 –auto-generate-sql –auto-generate-sql-load-type=write –engine=myisam –number-of-queries=200 -S/tmp/MySQL1.sock

Benchmark

Running for engine myisam

Average number of seconds to run all queries: 0.016 seconds

Minimum number of seconds to run all queries: 0.016 seconds

Maximum number of seconds to run all queries: 0.016 seconds

Number of clients running queries: 50

Average number of queries per client: 4

Benchmark

Running for engine myisam

Average number of seconds to run all queries: 0.265 seconds

Minimum number of seconds to run all queries: 0.265 seconds

Maximum number of seconds to run all queries: 0.265 seconds

Number of clients running queries: 100

Average number of queries per client: 2

MySQL压力测试工具中指定数据库的测试:

–create-schema,指定数据库名称

–query,指定SQL语句,可以定位到某个包含SQL的文件

例如:

shell>MySQLslap –defaults-file=/u01/MySQL1/MySQL/my.cnf –concurrency=25,50 –iterations=1 –create-schema=test –query=/u01/test.sql -S/tmp/MySQL1.sock

Benchmark

Average number of seconds to run all queries: 0.018 seconds

Minimum number of seconds to run all queries: 0.018 seconds

Maximum number of seconds to run all queries: 0.018 seconds

Number of clients running queries: 25

Average number of queries per client: 1

Benchmark

Average number of seconds to run all queries: 0.011 seconds

Minimum number of seconds to run all queries: 0.011 seconds

Maximum number of seconds to run all queries: 0.011 seconds

Number of clients running queries: 50

Average number of queries per client: 1

以上的相关内容就是对MySQL压力测试工具的介绍,望你能有所收获。
