Biggest opportunity: Swap “performance” and “caching” for “backend” and “debugging”. “performance” isn't earning its slot: you're not in the first 24 results for its own search. “backend” sits at #4 untagged, close enough for a declared tag to move it up. “caching” isn't earning its slot: it only gets you to #18. “debugging” sits at #5 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 →2.7%
of downloads still active
At least 500K of 18.6M lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,101 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 3 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 “performance” and “caching” for “backend” and “debugging”. “performance” isn't earning its slot: you're not in the first 24 results for its own search. “backend” sits at #4 untagged, close enough for a declared tag to move it up. “caching” isn't earning its slot: it only gets you to #18. “debugging” sits at #5 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- Slipping on “caching”. Down 8 places since 2026-09-17, now #18. Check what shipped around then, and what moved above you.

Estimated active installs
The public count shows “500K+”. Our estimate pins where the real number sits.
Crossed into this band 2 months ago and a band this size takes about a year or more to cross, so the real count is still just over 500K.
At the current install trend, crossing 600K+ in roughly 102 days.

Truly, I would recommend this plug-in. Fast, efficient, and once you make the normal modifications to your WordPress installation, it works like a charm.The only concern is, if you flush your cache, it flushes the whole DB number the WordPress Site is using in Redis, and whatever else was in that DB number is gone too. This means that if you want to have to-site accurate cache flushes, you will need to setup a DB number per WordPress site you are hosting.Author, please see this and make the flush scoped to the site’s cache match, not the whole Redis DB number. Yes this isn’t a world ending detail… but could be a chance for a good optimization. Thank you again for this plug-in!!

Easy to use and just does the job!!!!

I installed Redis Object Cache a couple of days ago and the diagnostics shows me it is saving on a good proportion of MySQL database hits. The author responded quickly to my questions on the support forum. Every WordPress site should have an object cache and, although it is early days for me, I can recommend this plugin.

It would be wildy easier to use if it was possible to change the IP. Sometimes you have multiple containers working alongside each other in a complex network. This plugin just defaults to presuming Redis is local. Sure I can edit loads of files to fix this.. but then the plugin is pointless if I am just leaning on CLI.Beyond this, it adds adverts to the wordpress dashboard. A feature which should not even be possible in my view. I get it, you need to make money. But shoving adverts all over my website just makes me never ever want to spend a dime on your products.

Amazing plugin. But if you are using it on some serious projects don’t forget to disable Redis Cache for your ERP imports/wp cli etc in wp_config.

recently I could config & install PhpRedis on my dedicated server and im using the Redis cache plugin with my wordpress setup Nice work bro Thanks a lot ❤️ I also recommend using the Pro version (Object Cache Pro) with more options and better performance objectcache[DOT]pro

When I was getting to know about object cache and other things, I was worried about spending lots of time setting it up. But I rarely face any error and it was quick. 🙂
