atec Cache APCu

Description

This plugin provides a super fast APCu-Object-Cache and the only APCu based page-cache plugin available.
Using an object-cache will speed up your site – APCu is the fastest cache, compared against the two other memory-based cache options Redis and Memcached.

– Object caching involves storing variables and database queries thereby speeding up PHP execution times. This reduces the load on your server, and delivers content to your visitors faster.
– Page caching refers to caching the content of a whole page on the server-side. Later when the same page is requested again, its content will be served from the cache instead of regenerating it from scratch.

Requires PHP APCu extension.
Lightweight (160KB) and resource-efficient.
Backend CPU footprint: 6 ms.
Frontend CPU footprint: <1 ms.

3rd party as a service

Once, when activating the plugin, an integrity check is requested from our server (https://atecplugins.com/) – if you give your permission.

Installation

  1. Upload the plugin folder to the /wp-content/plugins/ directory or through the Plugins menu.

FAQ

  • Use WP-CLI
    If you use WP-CLI to run .php scripts, please set “apc.enable_cli=1” in your php.ini – otherwise object-cache will not work.

Started to use this plugin to get my Objekt-Cache to a better use and a bit more site speed. I noticed some options that hadn’t changed like getting my WooCommerce live and after a bit of digging I noticed that this plugin was preventing the changes form being saved. Today I woke up to a blank Frontsite and a blank admin dashboard and I panicked a bit. After deactivation this plugin everything worked fine again. Can’t activate the options of this plugin when its installed anymore so I wasn’t able to recreate the problem and check the debug log. But at least my whole site didn’t get blank anymore.

I spent all day trying to find the source of my website issues, downloaded several other plugins with very little results without a paywall. I narrowed my search and ended up finding Atec page with several very useful plugins. I ended up purchasing the PRO one time fee for the license which unlocked the Atec Deploy plugin. Extremely impressed with the (light weight) resources the plugins offer. I think all the features are very simple for any user to understand, with and impressive amount of detail and configurations that are all compressive. Their tech support is really responsive and answered all my questions. I would highly recommend this to any professional or beginner web developer. Thanks for creating these plugins!

Thanks to this plugin I solved several problems on the site, from fast loading to space used by the cache and when I needed clarifications the support was fast and effective 💯

Dies ist nicht das erste APCu Plugin, das ich installiert habe. Zuvor hatte ich den “APCu Manager” von PerfOps ausprobiert/deaktiviert/ausprobiert…. irgendwie habe ich keinen Unterschied bemerkt, nur die Fehlermeldung im Wordpress “Website-Zustand” änderte sich von “Du solltst einen Object-Cache verwenden” zu irgend etwas anderem. Eigentlich war das Thema für mich erledigt, dann stolpere ich mehr zufällig über dieses kleine Plugin. Ja, es ist wunderbar klein! Und schnell! Ich habe nie etwas gemessen, doch mit dem “atec Cache APCu” bemerkt man einen deutlichen Unterschied zu vorher. Ich behalte es! Kompatibel mit WooCommerce (der Objekt Cache stört beispielsweise auch keinen Currency-Switcher, wie ein Page-Cache es regelmäßig tut). Auch keine Fehlermeldung mehr im Website-Zustand! Dieses gratis Programm kommt zusätzlich mit einem kleinen Page/Seiten-Cache onboard, der automatisch alle Nicht-Woocoomerce-Seiten cached. Kann man aktivieren oder deaktivieren, mehr nicht. Wenn man mag, bekommt man für 39 Euro auch eine “Pro” Version und damit zugleich ein ganzes Bundle an nützlichen Plugins von Atec. Bei der Pro-Version soll der Page-Cache besser sein. Das weiß ich nicht, eigentlich ist dieses kostenlose Plugin den Preis aber schon wert! 😉 Support vom Autor ist notfalls auch möglich. Die Kurzversion: Unbedingt testen! 10 Sterne!

HelloEven though I changed the memory consumption settings via PHP, there is no change on the plugin in the Admin panel. Is there a reason for this or am I doing it wrong? Thanks
