About this plugin
4 is built around an adaptive Optimization Lab rather than a fixed list of generic optimization switches.
The Lab creates a local site profile, measures cleanup opportunities, estimates autoloaded option data through WordPress APIs, generates site-specific recommendations, stores a local baseline, and lets administrators compare later scans against that baseline.
Key features:
- Explainable Opportunity Map: each finding answers what it means, what was measured, and what a non-technical administrator should do next.
- Impact Passport: records Optimizer actions with before/after local measurements so administrators can see what actually changed.
-
Read-only heavy-autoload view: surfaces the largest always-loaded options without automatically deleting or disabling unknown data.
-
Local Optimization Lab with an on-demand site scan.
- Site-specific recommendation engine based on measured local conditions.
- Baseline and before/after comparison.
- Local scan history (last 10 scans).
- Conservative one-click optimization profile with settings rollback.
- Approximate autoload footprint measurement using WordPress-loaded options.
- Revision, expired transient, auto-draft, trash and junk-comment opportunity detection.
- Cleanup of revisions, expired transients, auto drafts, trash, and spam/trash comments.
- Configurable revision retention.
- Database table optimization.
- Advanced CSS and JavaScript handle controls for experienced administrators.
- Heartbeat controls for dashboard, editor, and front end.
- Optional removal of common WordPress front-end overhead.
- No cloud account and no automatic telemetry.
The Lab Score is an internal prioritization indicator based only on the local conditions the plugin measures. It is not PageSpeed, Core Web Vitals, a hosting benchmark, or a guarantee of performance improvement.
The conservative profile changes only Erfika Optimizer settings and stores the previous plugin settings so they can be restored. Destructive database cleanup remains a separate manual action and is never run by the conservative profile.
