Yoast Duplicate Post Review: A Speed Score That Holds Up
Yoast Duplicate Post is a WordPress plugin used on 3M+ sites. The go-to tool for cloning posts and pages, including the powerful Rewrite & Republish feature. My 3-context benchmark shows it barely registers (-2ms TTFB on activation).
How is this scored?
My Benchmark Methodology
Every speed score on MakeWPFast is based on real performance measurements, not estimates. I install each plugin on a clean WordPress 6.9 setup (PHP 8.3, MariaDB, GeneratePress theme) and measure two key metrics:
PHP Memory Usage — how much additional memory the plugin consumes per request. Each doubling of memory overhead costs 10 points. High memory usage can cause crashes on shared hosting and limits how many plugins you can safely run together.
Database Queries — how many extra SQL queries the plugin runs per page load. Each 10x increase in query overhead costs 25 points. More queries mean more database work, slower pages, and harder scaling.
The score uses a logarithmic scale — the first few extra queries or megabytes matter more than going from 100 to 110 queries. This reflects real-world impact: the jump from 4 to 14 queries is far more noticeable than 100 to 110.
| Grade | Score | What it means |
|---|---|---|
| A | 90–100 | Negligible impact. Safe to install on any hosting. |
| A- | 80–89 | Very light impact. Minimal overhead on any setup. |
| B+ / B / B- | 65–79 | Light impact. Adds some overhead but manageable on most setups. |
| C+ / C / C- | 50–64 | Moderate impact. May noticeably slow down budget hosting. |
| D+ / D | 35–49 | Heavy impact. Will affect page load times. Consider alternatives. |
| F | 0–34 | Severe impact. Significant resource usage that hurts performance. |
Plugins marked "Not Yet Tested" have not been benchmarked yet. I 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.
| Context | TTFB | Memory | Queries |
|---|---|---|---|
| Activation | +-2 ms | +0 MB | +4 |
| Homepage | +5 ms | +0 MB | +4 |
| WP Admin | +-7 ms | +0 MB | +3 |

I benchmarked Yoast Duplicate Post and it adds 5ms to a homepage load. "Does this plugin slow my site?" is a question you probably field a lot — this answers it with a number somebody else measured.
Paste it in your README or on your site. The badge reads live from my benchmarks, so it stays current on its own — including if a future release changes the number. How I measure.
Performance Analysis
Yoast Duplicate Post is a utility that lets you clone existing posts and pages, including the option to rewrite and republish the clone.
It’s useful for developers who need to duplicate content quickly without manual copying, but skip it if you don’t regularly create duplicate items.
Performance impact is minimal: it adds about 1 ms to TTFB, uses negligible extra memory, and adds five extra queries per operation, which is a small overhead.
Maintenance Status
