Rolling snapshots of WordPress execution time, memory, and query counts — catch performance regressions the moment they start, not after clients report slowdowns.
Individual diagnostic checks tell you what a WordPress site looks like right now. Performance Baselines tell you whether it's getting better or worse over time. The module automatically captures rolling snapshots of WordPress execution time, peak memory, and database query counts across frontend page loads — and runs trend analysis across those snapshots to classify performance as improving, stable, or regressing.
Compares the most recent WordPress performance snapshots against the rolling average and classifies each metric independently as Improving, Stable, or Regressing. A regression in execution time without a change in query count often points directly to a new slow hook or blocking external request.
Every captured snapshot is stored in a sortable table showing timestamp, execution time, peak memory, database query count, PHP version, and active plugin count at time of capture. Plugin count changes make post-update WordPress performance regressions immediately visible.
WordPress performance snapshots are captured automatically during normal frontend page loads — no manual triggering required. The capture hook adds negligible overhead and stores only the numeric metrics needed for trend analysis.
Because snapshots are timestamped and include active plugin count, you can directly compare WordPress performance before and after a plugin update, a theme change, or a hosting migration. The change point is immediately visible in the historical table.
Snapshots contain only system-level WordPress metrics: execution time, peak memory, query count, PHP version string, and plugin count. No URLs, user data, request content, or IP addresses are stored at any point.
The module retains a rolling window of recent snapshots — enough to produce meaningful trend data without accumulating unbounded WordPress database growth. Older snapshots are pruned automatically once the retention limit is reached.
The capture overhead is negligible — a few microseconds to measure and store the metrics at the end of each WordPress request. The stored data is a handful of integers per snapshot.
The trend engine compares the rolling average of the most recent snapshots against the average of the preceding window. If execution time has increased by more than a threshold percentage, the trend is classified as Regressing. If it has decreased meaningfully, Improving. Otherwise Stable.
No. Performance Baselines is a Pro-exclusive module.
Long-term WordPress performance history — so regressions are caught in minutes, not discovered in client complaints.
Performance Baselines is included in every Pro plan alongside all seventeen diagnostic modules.
