Just basically be optional to all Redis object cache users. Thanks! ![](https://secure.gravatar.com/avatar/9a52a7a932b6419c9e6f06cae198dc8b3e3c4ba2a72d8dfc56fbf304ab35819f? s=60&d=retro&r=g) ### 󠀁[Works «out of box». Thx!](https://wordpress.org/support/topic/works-form-the-box-thx/)󠁿 [jasper2007](https://profiles.wordpress.org/jasper2007/) December 16, 2019 Just installed it to WP 5.3.1 works great, much better TTFB now. If you installed it from WP admin don’t forget change page-cache-red to pj-page-cache-red in your symlink to get it work. ![](https://secure.gravatar.com/avatar/8f9b953dff054059a14b177cd54c7cf15839c1df30c6980fd3d2d0c674020f47? s=60&d=retro&r=g) ### 󠀁[Sorry, it’s not working](https://wordpress.org/support/topic/sorry-its-not-working-3/)󠁿 [Szymon Scholz](https://profiles.wordpress.org/uzerus/) January 3, 2019 Stress test says everything for me :/ ![](https://secure.gravatar.com/avatar/1a788fb3bad207320853f2be45162fc6548696896e0d23ff2f8c84388c6c3722? s=60&d=retro&r=g) ### 󠀁[Real speed! Great](https://wordpress.org/support/topic/real-speed-great/)󠁿 [seodilip](https://profiles.wordpress.org/seodilip/) October 25, 2018 A must have for Woocommerce webmasters. This one’s a killer. However, configuring should be done with care! ![](https://secure.gravatar.com/avatar/8ab38b2fbbfde2492bd3614ccc90613e9be900afe3d2dd3a2f1b8b1f66688672? s=60&d=retro&r=g) ### 󠀁[Amazing!](https://wordpress.org/support/topic/amazing-1704/)󠁿 [blysq23](https://profiles.wordpress.org/blysq23/) February 7, 2018 We used this plugin on a number of websites. Its caching method is a lot better than any other caching plugins I’ve tried. Most of them actually SLOW DOWN your website which is awful. Avoid object caching as it doesn’t work well with WordPress. This is one of the few plugins that actually do the job and do it well. The cache invalidation is always spot on with this plugin. As soon as you set it up you never have to worry about a thing. Debugging is also a breeze with the plugin as it adds an http header informing you whether you hit a cached version or not. Even tho it hasn’t been updated in a very long time, it still works without any issues whatsoever. Thank you for this great plugin. ![](https://secure.gravatar.com/avatar/6870b0cd2a26009b4c93b0c356e1c072af485685432957f7ce8b31978af3c24f? s=60&d=retro&r=g) ### 󠀁[First impression with replicated redis cache](https://wordpress.org/support/topic/first-impression-with-replicated-redis-cache/)󠁿 [kochtopf](https://profiles.wordpress.org/kochtopf/) September 3, 2016 This is the real deal for speed freaks. Benched it against my favorite disk cache( Hyper Cache) – it’s around 10 times faster. It can work on a separate/remote redis server too. Pro: Super fast compared to disk caches (10x faster remote – 20x faster if redis is on localhost). -live cache can be replicated to a hot backup -despite the release number (v0.8) it is stable and has no issues with anonymous comments. Cache invalidation for post and feeds works nicely (Still need to test the /pages,/ tag, /categories – the usual WP stuff…)- -Very lightweight and CPU friendly. Open source and well supported. -compresses pages in memory -low CPU use. Can run on low-end hardware Cons: Not every plug likes it. Some cookies (like PHPSESSID) must be excluded to get pages cached. -no easy way to change/update cached content by hand. For example, change a sitebar widget and you must flushall your redis database if you run a high TTL. Disk caches lets you grep/sed content much easier. -need some free memory (48gb for some 3000 posts).
