How WooCommerce Affects Your WordPress Speed
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 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.
| Grade | What it means |
|---|---|
| A / A- | Negligible impact. Safe to install on any hosting. |
| B+ / B / B- | Light impact. Adds some overhead but manageable on most setups. |
| C+ / C / C- | Moderate impact. May noticeably slow down budget hosting. |
| D+ / D | Heavy impact. Will affect page load times. Consider alternatives. |
| F | 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.
Maintenance Status
