Object Cache
The Object Cache performance addon for freistilbox is based on Valkey, an open-source, high-performance key/value datastore.
What is Valkey?
Valkey is an open-source, in-memory data store that your Drupal or WordPress site can use as an object cache. It’s a community-maintained fork of Redis and fully compatible with existing Redis caching plugins.
Why use an object cache?
Every time a visitor loads a page, your CMS runs database queries to fetch content, configuration, and other data. Many of these queries return the same results repeatedly. Your site’s menu structure, for example, rarely changes between requests.
An object cache stores these query results in memory. When your application needs the same data again, the cache returns it in microseconds instead of waiting for a database round-trip. This reduces load on your MySQL database and makes your site respond faster, especially under heavy traffic.
How Valkey works on freistilbox
When you enable the Valkey addon, we provision a dedicated Valkey instance for your website. Your application connects to this instance using connection details we provide, and all cached data stays isolated from other customers’ sites.
Because Valkey stores data in memory only, the cache starts empty whenever the service restarts. Your site rebuilds it automatically as visitors request pages — within a few minutes of normal traffic, it’s back up to speed.
Benefits for your sites
Memory reads take nanoseconds; database round-trips take milliseconds. That gap adds up fast under load. Pages get faster across the board, fewer queries reach MySQL, and during traffic spikes your site keeps moving instead of queuing up behind a struggling database.
