Memcached < File < Redis < SQLite < APCu

Kirby ships with built in support for File, Memcached and APCu Cache Drivers. I created a Redis Cache Driver which is imho best suited for larger caches. If your hosting does not support Memcached, APCu or Redis then your next best choice is this SQLite Cache Driver.

2 is enough and about 35% faster

Let's imaging this typical scenario: During a single pageview you need to access, 100 cached values. Some of them already exist, some not, some need to be refreshed and yet others need to be deleted. With a File Cache this would cause at least 100 filesystem operations in total. Using this SQLite Cache you will have only 1 file read and maybe 1 file write per pageview no matter how many values you get, update or remove. ✌️ But reading and writing data to SQLite is not instantaneous, so it will be at least 35% faster.


Cache methods

$cache = \Bnomei\SQLiteCache::singleton(); // or
$cache = feather();

$cache->set('key', 'value', $expireInMinutes);
$value = feather()->get('key', $default);



sqlite : 0.075334072113037
file : 0.11837792396545

ATTENTION: This will create and remove a lot of cache files and sqlite 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 Feather with Lapse or Boost

You need to set the cache driver for the lapse plugin to sqlite.


return [
    'bnomei.lapse.cache' => ['type' => 'sqlite'],
    'bnomei.boost.cache' => ['type' => 'sqlite'],
    //... other options

Setup Content-File Cache

Use Kirby 3 Boost to setup a cache for content files.


The plugin comes with aggressive defaults for SQLite Pragmas to optimize for performance. You can change these in the settings if you need to.


bnomei.sqlite-cachedriver. Default Description
store true keep accessed cache items stored in PHP memory for faster recurring access
store-ignore `` if key contains that string then ignore
