Redis vs Memcache vs APCu – object cache comparisons

“The big three in the world of object-caching: Redis – fast but might not be supported everywhere. Possibly the fastest/best option if you can get it to work. Memcache – the old (but very stable standard). Most people who haven’t played with Redis yet will go with this. I love it. APCu – very fast because it doesn’t write anything to the disk, simply stores it as is. Can cause problems or performance-loss in certain environments (clusters, server restarts, low memory, etc). FYI: some people say APCu is outdated and that you shouldn’t use it. Some old” https://wpjohnny.com/redis-vs-memcache-vs-apcu-object-cache-comparisons/#:~:text=The%20big%20three,Some%20old
