Mysqlslap is a benchmark tool provided by mysql. It has the following advantages: Data Query, simple syntax, and flexible and easy to use. this tool can simulate multiple clients to concurrently send query updates to the server, and provides performance test data and Performance Comparison of multiple engines. msqlslap provides an intuitive verification basis before and after mysql performance optimization. It is recommended that system O & M and DBA personnel master some common stress testing tools, in order to accurately master the user traffic ceiling supported by online databases and their adequacy.

Detailed tool parameters

-- Help: Display help

-- Concurrency indicates the number of concurrent tasks. multiple concurrent tasks can be separated by commas (,).

-- Engines test engine. Multiple engines are separated by delimiters.

-- How many times does iterations run these tests?

-- Auto-generate-SQL script generated by the SQL System

-- Auto-generate-SQL-load-type: whether to test whether the read or write operations are mixed or not (read, write, update, mixed)

-- Number-of-queries

-- Debug-info: Additional CPU and memory information output

-- Number-int-cols: number of int fields in the test table

-- Auto-generate-SQL-add-autoincrement automatically adds the auto_increment column to the table generated

-- Number-char-cols: number of char fields in the test table

-- Create-schema Test database

-- Query: run the test with a custom script

-- Only-print: If you only want to print and see what the SQL statement is, use this option.

2. Test the instance (single concurrency)

Note: To test 100 concurrent threads, the test times are once. The SQL test script, read, write, and update hybrid test are automatically generated. The test engine is myisam, runs 10 queries and outputs cpu resource information.
