How contact-form-7-add-confirm Affects Your WordPress Speed

Our Benchmark Methodology

Every speed score on MakeWPFast is based on real performance measurements, not estimates. We install each plugin on a clean WordPress 6.9 setup (PHP 8.3, MariaDB, GeneratePress theme) and measure the difference in three metrics:

TTFB (Time To First Byte) — how many milliseconds the plugin adds to server response time. This is the most important factor (50% of the score) because it directly affects every page load.

Memory usage — how much additional PHP memory the plugin consumes per request (30% of score). High memory usage can cause crashes on shared hosting.

Database queries — how many extra SQL queries the plugin runs per page load (20% of score). More queries mean more database work on every request.

Plugins marked "Not Yet Tested" have not been benchmarked yet. We do not estimate or guess scores — if there is no measured data, there is no grade.

Note: Benchmarks measure a plugin in isolation on a clean install. Real-world impact varies based on your hosting, other plugins, and how the plugin is configured.
