MySQL 5.7 Benchmark

Structured Markdown documentation to diagnose, measure, and optimize MySQL.

This page is original PmaControl documentation. It keeps a practical index structure for MySQL optimization work, without copying third-party content or depending on an external product.

Objective

MySQL 5.7 remains present in old environments. Benchmarks must account for end of support and limitations around query cache, redo, and the optimizer.

What to Check

  • Data and volume close to production.
  • Buffer pool warmup before measurement.
  • Separate measurement of average, p95, and p99 latency.
  • Capture CPU, I/O, memory, connections, and MySQL errors.
  • Comparison across several iterations.

Expected Result

The deliverable must indicate the tested configuration, workload, observed limits, and operational recommendation.
