Biggest opportunity: Swap “api” and “cache” for “flush” and “wp cache”. “api” isn't earning its slot: you're not in the first 24 results for its own search. “flush” sits at #6 untagged, close enough for a declared tag to move it up. “cache” isn't earning its slot: it only gets you to #13. “wp cache” sits at #11 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 →2.4%
of downloads still active
At least 10K of 421.7K lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,100 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 11 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 “api” and “cache” for “flush” and “wp cache”. “api” isn't earning its slot: you're not in the first 24 results for its own search. “flush” sits at #6 untagged, close enough for a declared tag to move it up. “cache” isn't earning its slot: it only gets you to #13. “wp cache” sits at #11 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “cache”. #13 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

Nice one! Decreased response time by almost 60%.
Read on wp.org ↗ - ★★★★★ zerfl1.2y ago
This plugin is excellent and works exactly as advertised. Definitely worth a perfect rating. I do think the FAQ could be expanded a little more to mention process_cache_relations for custom REST endpoints, however. I only found my solution buried in other users’ threads. I had wrongly assumed that providing the object type manually via the determine_object_type hook was equivalent to making object relationships work, which is clearly not the case. Overall, a really great plugin and very well thought-out.

Using this plugin has made my API for filtering products go from finishing the filtering and reaching the user in 2.3 seconds to reaching the user in about 200 ms. A huge improvement indeed. However, I’ve noticed two things that slowly drive me insane: The add_filter for hiding the REST API button in the admin panel isn’t working. Why does this need a filter at all? Just make it a setting. I don’t get it. There is a serious lack of settings for this plugin. What if I want to cache one API route shorter than another? That’s currently impossible. Where’s the “regenerate all caches” button? This might very well be the only caching plugin without such a button. Yes, it has a “Clear all”, but no “Regenerate all”. This is a solid 5/5 if they add the above. I’ve yet to find a better solution that doesn’t involve Cloudflare. Thanks for the plugin! This topic was modified 1 year, 3 months ago by hirngesicht.

Installed on suggestion of WP Maps, made a big difference in load speeds of maps.

Great plugin! I use it for a headless WordPress instance with Nuxt 3, and it works perfectly fine. The only thing I needed to change was the API endpoint since I created a custom endpoint to the route. But the FAQ cleared this up quickly and it works flawlessly. As a small suggestion I’d propose to add this option to the plugin’s settings page for easier access.

It’s been years since I touched wordpress or php. My usecase was very tricky and not doable out of the box. It worked out great in the end and the response time is now 4-5 times quicker. Amazing. But the best part is how quickly Richard answered to my noob questions and even fixed a bug I found. If you ever need a beta tester! Hit me up <3

对于 WordPress REST API 提速非常明显，非常棒！ 并且还可以当发布文章、分类、Tag… 时自动刷新缓存，完全不用担心缓存时间过久问题。 但是我还有一个问题，这个缓存的数据是存储到哪里的，是存储在 Redis 中的吗？
