Simple Cache


Simple Cache was constructed after getting frustrated with the major caching plugins available and building sites with developer-only complex caching solutions that get millions of page views per day. Simple Cache promises the following:

  • Extremely simple one-click install. There is an on-off switch. That’s it. No need to wade through 50 complicated settings.
  • Simple Cache makes your site run very fast so you can handle lots of traffic.
  • Extremely easy to delete. Don’t like the plugin? You can remove it, and your website won’t break.
  • Easily clear the cache if you need to.
  • Enable gzip compression
  • Want to get advanced with object caching (Memached or Redis)? An advanced mode is available that will automatically setup Batcache and Memcached/Redis for you.

If you need your site to run fast, don’t have time to mess with complicated settings, and have been frustrated by other caching plugins, give Simple Cache a try.

Simple is the best.

I tried a few other cache plugins and settled on Simple. It's simple and lightweight, and fulfill the cache job. Besides, it works on both Apache and Windows server, since we have two websites, one hosting on Windows server, another on Linux. Thank you.

It just WORKS.

Struggled with other caching plugins. This one really is simple and it just WORKS. Turn it on, enable gzip in advanced options.. page load time went from 9 second to 2.5 seconds instantly.


В аккаунте хостера появилось сообщение о жуткой нагрузке, потратил 2 дня на поиск проблем, так как сайтов на аккаунте много. В итоге нашел проблему, этот плагин генерирует почти полторы тысячи непонятных запросов, сайт открывается ужасно медленно и создает высокую нагрузку.


Awesome plugin, installed it and used advance mode and under a minute and you are done. 🙂

BEST CACHE PLUGIN – happy for 3 months now

Tried every cache plugin out there. They were all full of options and ultimately JUST SLOW. This was the first one that actually worked and also happened to be the simplest one to use. It was my programmer who thought of trying this one. He explained the developer was a well-respected one from 10up. I was using Redis at first for object cache but it would have some issues with exclude URL's so we switched over to Memcache and everything has been perfect. Later on, I switched back to Redis again and it was faster and also working. Ahhhh well. My home page is 1mb in size and loads in 500-800ms using Simple Cache + Cloudflare CDN. I'm on 4-core VPS, btw. My site is blazing's even faster than with LiteSpeed Cache, which is supposed to be faster since it's a server-level cache. I don't know how that's even possible but I'm guessing client-side object caching takes less work than doing a full-page server cache. Hope someone can explain that to me.
