Measured Speed Score

How is this scored?

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 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. 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.

Performance Analysis

WooCommerce is a widely used e-commerce plugin that lets you create an online store quickly and manage orders, payments, and inventory. It’s aimed at anyone who wants to sell products on WordPress without learning complex e-commerce software, and it’s suitable for small to large stores that need a reliable way to handle sales.

The plugin’s 90‑out‑of‑100 rating and over 7 million active installs show it’s popular and generally working, but the benchmark deltas indicate added overhead: a 35 ms TTFB increase, 12 MB more memory use, and 66 more queries per request, which can slow page response and raise server load.

If you’re okay with a modest performance hit and have a lightweight theme, WooCommerce works fine. Skip it if you need the absolute fastest possible page load or want to keep your site’s memory usage very low.

Frequently Asked Questions

Why does WooCommerce add measurable overhead?

Our benchmark recorded a +9ms TTFB delta and roughly 6MB additional memory on activation. That earned WooCommerce a speed score of D — usable, but doing more work on every request than it likely needs to.

Can I run WooCommerce without performance issues?

You can mitigate WooCommerce's +9ms TTFB cost with full-page caching and by disabling features you don't use, and the plugin runs on 7M+ active sites — so the issues we measured are tractable, just not invisible.

Does WooCommerce slow down WordPress?

WooCommerce has an estimated speed score of F. It may noticeably affect your site speed. Consider alternatives if performance is critical.

Is WooCommerce still maintained?

WooCommerce was last updated on 2026-02-10. It has 7.0M+ active installations, indicating it is actively maintained and widely trusted.
