If you've seen a recommendation to use a persistent object cache in your WordPress website's Site Health page, you may be curious about what it is and how it can benefit your website's performance.
Object Caching is a technique used to store frequently used data in a cache to reduce the load on your website's database. By storing data in a cache, your website can quickly retrieve it instead of querying the database every time the same data is requested, resulting in faster load times and improved overall performance.
Redis and Memcached
The most commonly recommended object caching solutions for WordPress are Redis and Memcached, which are robust and powerful caching systems.
However, setting up and managing a Redis or Memcached server, along with the additional database ID, can be complex and challenging for some website owners.
Recommended WordPress Object Cache Plugins
Fortunately, there are object caching plugins available for WordPress that are easy to use and provide excellent performance without the need for a separate server or database ID while also offering better performance due to lower latency.
Two Redis and Memcached alternatives which we recommend are:
SQLite Object Cache
The SQLite Object Cache plugin utilizes SQLite, a self-contained, serverless, and zero-configuration database engine, as the caching mechanism. It offers lower latencies compared to Redis and Memcached, resulting in faster data retrieval and improved website performance. Additionally, it doesn't require a separate server or database ID, making it a convenient choice for website owners looking for a simple caching solution.
Docket Cache
Another excellent option is the Docket Cache plugin, which is powered by OPCache, a built-in opcode caching engine in PHP. Docket Cache offers robust and efficient caching, resulting in faster load times and reduced database queries. It also provides advanced features like auto-cleanup and auto-preloading, which further enhance the performance of your WordPress website.
In conclusion, implementing object caching is a crucial step in optimizing your WordPress website's performance. While Redis and Memcached are commonly recommended, the SQLite Object Cache and Docket Cache plugins are excellent alternatives that offer simplicity, convenience, and superior performance.
Both the SQLite Object Cache and Docket Cache are fully compatible with our cPanel Cloud Hosting, Cloud Reseller Hosting and Managed WordPress Hosting services and we highly recommend using one of them for improved website performance without the hassle of complex setup.
Important Note
It's crucial to have only one persistent Object Cache plugin enabled for your WordPress website.
If you decide to use either the SQLite Object Cache or Docket Cache plugins mentioned above, make sure to set the Object tab in the LiteSpeed Cache plugin to OFF to avoid conflicts and ensure optimal performance.
