MySQL Throughput and QPS

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.

Reading

Throughput shows how many operations the server absorbs per second. Stable QPS with rising latency often signals progressive saturation.

Useful Measurements

SHOW GLOBAL STATUS LIKE 'Questions';
SHOW GLOBAL STATUS LIKE 'Threads_running';
SHOW GLOBAL STATUS LIKE 'Slow_queries';
SHOW GLOBAL STATUS LIKE 'Aborted_clients';

Diagnosis

Always compare the metric with application load and time. An isolated counter is not enough: the per-minute delta and correlation with incidents provide the usable signal.

Possible Actions

  • Identify the responsible queries or connections.
  • Check MySQL and system limits.
  • Test a targeted correction, then measure the same metric after the change.
