Memcached < File < Redis < SQLite < APCu
Kirby ships with built in support for File, Memcached and APCu Cache Drivers. APCu is widely available and performs great. It's only drawback is the limited memory size compared to SQLite or Redis.
Usually each call to the same cached item, even repeated calls in the same http request, would yield repeated requests to the APCu cache. With the in-memory store of this plugin retrieved items will be stored in a PHP array for the current http request and returned from there without the round trip to APCu. This might increase total memory usage of your PHP script but significantly speeds up repeated calls. You can turn of this behaviour in the settings if you do not need it.
Kirby removes expired cached items only if they are requested again and then deemed to be expired or when the cache is flushed completely. This might result in long expired items taking up memory in the cache.
The default APCu implementation has no active garbage collection but only removes expired cache items when running out of memory. That is a perfectly fine strategy. This plugin minimizes said behaviour by activly purging expired items.
$cache = \Bnomei\ApcuCache::singleton(); // or $cache = apcugc(); $cache->set('key', 'value', $expireInMinutes); $value = apcugc()->get('key', $default); apcugc()->remove('key'); apcugc()->flush();
apcugc : 0.026898145675659 file : 0.13169479370117
ATTENTION: This will create and remove a lot of cache files and apcu entries
No cache when debugging
When Kirbys global debug config is set to
true the complete plugin cache will be flushed and no caches will be read. But entries will be created. This will make you live easier – trust me.
How to use ApcuGC with Lapse or Boost
You need to set the cache driver for the lapse plugin to
<?php return [ 'bnomei.lapse.cache' => ['type' => 'apcugc'], 'bnomei.boost.cache' => ['type' => 'apcugc'], //... other options ];
Setup Content-File Cache
Use Kirby 3 Boost to setup a cache for content files.
