1.使用自動生成腳本測試數據庫性能

mysqlslap?-uroot -p123?-a?--debug-info?--concurrency=50,100 ?--number-of-queries=200?--engine=myisam,innodb

參數介紹?

-u : 用戶名

-p : 密碼

-a (--auto-generate-sql) : 自動生成sql腳本測試數據庫

--debug-info : 輸出debug信息,包括內存,CPU等

--concurrency : 用戶并發數,可填寫多個

--number-of-queries : 每個用戶的查詢次數

--engine : 需要測試的數據庫引擎

輸出結果:

Benchmark
