Biggest opportunity: Swap “database” and “performance” for “full page cache” and “wordpress cache”. “database” isn't earning its slot: you're not in the first 24 results for its own search. “full page cache” sits at #7 untagged, close enough for a declared tag to move it up. “performance” isn't earning its slot: you're not in the first 24 results for its own search. “wordpress cache” sits at #8 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →4.4%
of downloads still active
At least 20K of 455.6K lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,104 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Performance plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 14 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

What to do about it
- Swap “database” and “performance” for “full page cache” and “wordpress cache”. “database” isn't earning its slot: you're not in the first 24 results for its own search. “full page cache” sits at #7 untagged, close enough for a declared tag to move it up. “performance” isn't earning its slot: you're not in the first 24 results for its own search. “wordpress cache” sits at #8 untagged, close enough for a declared tag to move it up.

After installing this plugin I saw significant speed increases on page loading times. I’ve used it in combination with other page and browser cache plugins and have had no conflicts.

Docket Cache hat meine Seiten mit Elementor Pro, LearnPress und PMP deutlich schneller gemacht. Die Datenbankzeit ging praktisch auf null, die Anzahl der Queries wurde stark reduziert, und das Backend fühlt sich viel reaktionsschneller an. Einfach zu installieren, leicht zu konfigurieren und perfekt kompatibel mit WP Rocket und WP Optimize. Absolute Empfehlung!

Works flawless, really simple way to test object cache locally when developing, without needing to setup memchache or redis or similar. This topic was modified 9 months, 3 weeks ago by Pär Thernström.

It is really easy to set up and does its work flawlessly.

Hello from France! I only discovered your plugin two weeks ago. Usually I use Redis for all websites hosted on a VPS. However, Docket Cache rocks on (fast) shared hosting. Documentation is a delight: useful and detailed. I really loved that each option had a constant to configure it. And reading/searching the support forum really helped me. Long story short: I will deploy this plugin whenever it is possible. Have a great day! 🙂

This is the first cache that simply works with dynamic pages. My Pagespeed scores increased significantly. Other caches work but not on dynamic websites.
