MySQL mysqlslap load test utility

Stress Test Utility mysqlslap in MySQL/MariaDB/Aurora

mysqlslap - Slaps MySQL tables with a load of queries at a rate and concurrency that you set. Run a query multiple times against the server.

MySQL utility designed to simulate load test or stress test for a MySQL server and to report the timing of each stage.

Usage: mysqlslap [OPTIONS]
