MySQLslap是一個MySQL官方提供的壓力測試工具。以下是比較重要的參數：

 

–defaults-file，配置文件存放位置

 

–concurrency，并發數

 

–engines，引擎

 

–iterations，迭代的實驗次數

 

–socket，socket文件位置

 

自動測試：

–auto-generate-sql，自動產生測試SQL

 

–auto-generate-sql-load-type，測試SQL的類型。類型有mixed，update，write，key，read。

 

–number-of-queries，執行的SQL總數量

 

–number-int-cols，表內int列的數量

 

–number-char-cols，表內char列的數量

 

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壓力測試工具中指定數據庫的測試：

–create-schema，指定數據庫名稱

 

–query，指定SQL語句，可以定位到某個包含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
