This article introduces the CDSBen model, a machine‑learning‑based benchmark that translates real database transaction patterns into storage‑layer I/O workloads, enabling precise, isolated performance testing of the cloud‑native veDB storage system.
This guide explains how to use MySQL’s built‑in mysqlslap tool and the third‑party sysbench utility to perform comprehensive database stress testing, covering configuration changes, command examples, result interpretation, and additional CPU and I/O benchmarks for accurate performance evaluation.
Using sysbench, this study benchmarks MySQL 5.7.22 and MySQL 8.0.15 under read‑write, read‑only, and write‑only workloads with various sync_binlog and innodb_flush_log_at_trx_commit settings, revealing performance trends across different concurrency levels and highlighting that MySQL 5.7 often outperforms 8.0 in these tests.
This guide explains how to use MySQL's built‑in mysqlslap tool and the third‑party sysbench utility to simulate concurrent client loads, adjust server settings, run read/write and I/O tests, and interpret the resulting performance metrics for database optimization.
