MySQL Memory Calculator Comparison

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

Memory calculators are useful when they expose assumptions: simultaneous connections, per-session buffers, and OS margin.

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.
