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，並發數
–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
