Frequently Asked Questions

Common questions about Speedix

Minimal impact when configured properly. Use "Safe Mode" preset (10% sampling, 2ms threshold) for production sites. The plugin includes overload protection that automatically pauses profiling if overhead exceeds safe limits.

No. Speedix uses read-only profiling with built-in safety limits. If overhead gets too high, it automatically pauses for 1 hour. You can also disable at any time from Settings.

Debugging plugins show detailed info about the current request. Speedix takes a different approach - it aggregates performance data over time to identify persistent slow spots and trends across many page loads.

Check in order: 1. Profiling enabled? - Toggle must be ON in Settings 2. Page whitelisted? - Only pages in "Pages to Profile" are tracked 3. Sample rate? - At 25%, only 1 in 4 requests profile. Set to 100% for testing 4. Threshold too high? - Set to 0ms temporarily to capture all hooks 5. Correct page? - Ensure you're visiting a whitelisted page

Enable "Identify plugin sources" in Settings. Without this, hooks are captured but not attributed to specific plugins.

Appears when callbacks can't be traced to source files. Common causes: anonymous closures, dynamically generated functions, or code outside plugin/theme directories.

Yes, especially in Safe Mode. Sample rate ensures only 10-25% of requests are profiled, and overload protection prevents performance impact.

Default: 24 hours. Configurable from 1 hour to 7 days. Data is automatically cleaned up via WordPress cron.

The profiler measures uncached PHP execution. Cached pages bypass PHP entirely and won't appear in profiles - this is expected behavior since cached pages are already optimized.

Yes. Each site maintains its own profiling data. Network admins can access the dashboard on any site.
