How Much Does Jetpack Slow Down WordPress? We Measured It
Jetpack is a WordPress plugin used on 3M+ sites. Our 3-context benchmark shows it barely registers (-1ms TTFB on activation).
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.
| Context | TTFB | Memory | Queries |
|---|---|---|---|
| Activation | +-1 ms | +2 MB | +4 |
| Homepage | +1 ms | +2 MB | +3 |
| WP Admin | +6 ms | +2 MB | +12 |

Performance Analysis
Jetpack is a security and performance add‑on that bundles tools like backup, malware scan and a basic WAF into one lightweight package. It’s aimed at developers who want quick, one‑click fixes without diving into complex security configurations.
It works best for sites that need basic protection and occasional maintenance, not for those requiring a full‑featured security suite or zero‑impact performance.
Skip Jetpack if you are looking for a solution that doesn’t add any measurable overhead to your site’s load time or memory usage.
Maintenance Status
