mysql性能测试工具之mysqlslap

2019.01.28 17:33 621浏览

    mysqlslap是mysql自带的基准测试工具,优点:查询数据,语法简单,灵活容易使用.该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性能比较.msqlslap为mysql性能优化前后提供了直观的验证依据,建议系统运维和DBA人员应该掌握一些常见的压力测试工具,才能准确的掌握线上数据库支撑的用户流量上限及其抗压性等问题.

1.工具详细参数

--help      显示帮助

--concurrency      代表并发数量,多个可以用逗号隔开

--engines             测试的引擎,多个用分隔符隔开

--iterations           运行这些测试多少次

--auto-generate-sql      系统自己生成的SQL脚本来测试

--auto-generate-sql-load-type     测试的是读还是写还是两者混合的(read,write,update,mixed)

--number-of-queries                   总共要运行多少次查询

--debug-info                               额外输出CPU以及内存的相关信息

--number-int-cols                       创建测试表的 int 型字段数量

--auto-generate-sql-add-autoincrement        生成的表自动添加auto_increment列

--number-char-cols                  测试表的 char 型字段数量

--create-schema               测试的database

--query                          用自定义脚本执行测试

--only-print                            如果只想打印看看SQL语句是什么,以用这个选项

 

2.测试实例(单个并发)

[root@node2 bin]# ./mysqlslap -uroot -psystem --concurrency=100 --iterations=1 --auto-generate-sql --auto-generate-sql-load-type=mixed --auto-generate-sql-add-autoincrement --engine=myisam --number-of-queries=10 --debug-info 

Warning: Using a password on the command line interface can be insecure.

Benchmark

 Running for engine myisam

 Average number of seconds to run all queries: 0.209 seconds

 Minimum number of seconds to run all queries: 0.209 seconds

 Maximum number of seconds to run all queries: 0.209 seconds

 Number of clients running queries: 100

 Average number of queries per client: 0

User time 0.02, System time 0.09

Maximum resident set size 4684, Integral resident set size 0

Non-physical pagefaults 1476, Physical pagefaults 0, Swaps 0

Blocks in 0 out 0, Messages in 0 out 0, Signals 0

[root@node2 bin]#

说明:测试100个并发线程,测试次数1次,自动生成SQL测试脚本,读,写,更新混合测试,自增长字段,测试引擎为myisam,共运行10次查询,输出cpu资源信息

 

3.测试实例(多个并发)

[root@node2 bin]# ./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=/tmp/mysql.sock -uroot -psystem

 Number of clients running queries: 50

 Average number of queries per client: 4

Benchmark

 Running for engine innodb

 Average number of seconds to run all queries: 0.754 seconds

 Minimum number of seconds to run all queries: 0.560 seconds

 Maximum number of seconds to run all queries: 0.920 seconds

 Number of clients running queries: 100

 Average number of queries per client: 2

Benchmark

 Running for engine innodb

 Average number of seconds to run all queries: 0.860 seconds

 Minimum number of seconds to run all queries: 0.709 seconds

 Maximum number of seconds to run all queries: 1.173 seconds

 Number of clients running queries: 200

 Average number of queries per client: 1

[root@node2 bin]#

说明:测试50,100,200个并发,运行20次,存储引擎myisam和innodb,运行200次查询

 

4.测试实例(自定义sql语句)

[root@node2 bin]# ./mysqlslap  --concurrency=100 --iterations=1  --query='select * from tong.t;' --number-of-queries=10 --debug-info -uroot -psystem

Benchmark

 Average number of seconds to run all queries: 2.211 seconds

 Minimum number of seconds to run all queries: 2.211 seconds

 Maximum number of seconds to run all queries: 2.211 seconds

 Number of clients running queries: 100

 Average number of queries per client: 0

User time 0.05, System time 0.27

Maximum resident set size 7324, Integral resident set size 0

Blocks in 7104 out 0, Messages in 0 out 0, Signals 0

Voluntary context switches 3449, Involuntary context switches 40

[root@node2 bin]#

 

5.测试实例(检测脚本)

[root@node2 bin]# ./mysqlslap --create=/yourpath/Test1.sql --query=/yourpath/Test2.sql --concurrency=50,100,200 --iterations=20 --engine=myisam,innodb  -u root -psystem
