    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!!

    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. 🙂
