If you have ever wondered why some WordPress websites load in under a second while others crawl along taking three or four seconds to respond, the answer often comes down to caching. Specifically, WordPress object cache At FluxRunner, every managed WordPress hosting plan includes object cache as a standard feature at no extra cost. Some competitors charge up to $100 per month just to unlock this capability. In this post, we break down exactly what object caching is, why it matters, and how FluxRunner makes it available to every single customer on every plan.
What Is Object Caching?
Every time a visitor loads a page on your WordPress site, WordPress reaches into its database to fetch content, settings, user data, menus, and dozens of other pieces of information. For a typical page, this can mean 30 to 100 individual database queries happening in milliseconds. That is a lot of work happening in the background every single time someone visits your site.
Object caching solves this problem by storing the results of those database queries in a fast, temporary memory store. Instead of hitting the database every time, WordPress checks the object cache first. If the data is already there, it serves it instantly without touching the database at all. The site responds faster, uses fewer server resources, and handles traffic spikes far more gracefully.
Think of it like a notepad sitting on your desk. Rather than walking to the filing cabinet every time you need a piece of information, you write it down on the notepad for quick access. Object caching works the same way for your website.
What Is Redis Cache and How Does It Work?
Redis is the most widely used technology behind persistent object caching for WordPress. It is an open-source, in-memory data store that holds data in RAM rather than on a hard drive. Because RAM is much faster than reading from a disk or running a database query, Redis can serve cached data in microseconds.
By default, WordPress has a built-in object cache that only lasts for the duration of a single page request. Once that page finishes loading, the cache is thrown away. The next visitor has to start the whole process from scratch. Redis changes this by making the object cache persistent. It keeps that cached data alive between page loads, so repeat queries are served from memory instead of the database every single time.
This makes a huge difference for dynamic WordPress sites, especially WooCommerce stores, membership sites, and any site with logged-in users. These types of sites cannot rely solely on page caching because each user session is unique. Object caching is where the real performance gains come from in these cases.
Why Do Competitors Charge So Much for Object Cache?
Object caching requires a dedicated Redis server or process running alongside your website. That takes server memory and infrastructure to support. Most managed WordPress hosts treat this as a premium add-on because it costs them more to provision. Some charge $25 to $50 per month for a basic Redis add-on, and enterprise-tier plans at certain hosts can push the cost to $100 per month or more just for this one feature.
Hosts like WP Engine, Kinsta, and Pagely have historically gated Redis behind their higher-tier plans. That means small businesses, bloggers, and growing sites are often left paying slow database-driven response times on plans that do not include object caching. You end up paying more just to get performance that should come standard.
How FluxRunner Includes Object Cache on Every Plan
At FluxRunner, object cache is not a bolt-on feature. It is baked into the infrastructure for every WordPress site we host, from our entry-level Starter plan at $8 per month all the way up to our Full Power plan. You do not need to request it, pay extra for it, or configure it yourself. It is simply on and working from day one.
This is possible because of the way FluxRunner is built. Each WordPress installation on our platform runs on its own dedicated resources, including its own CPU allocation, dedicated RAM, and SSD storage. Every site gets the infrastructure it needs to run object caching without fighting for shared resources with other websites on the same server.
Our platform is powered by the Flux Network, the world’s first 100% decentralized blockchain-powered Web3 cloud. Sites are distributed across multiple nodes with dedicated resources per installation. This architecture naturally supports persistent in-memory caching because each site has isolated, consistent access to its own resource pool. There is no shared memory environment that would make object caching unreliable or expensive to scale.
What This Means for Your WordPress Site Speed
The real-world impact of object caching on WordPress performance is significant. Sites with object caching enabled typically see database query times drop by 50 to 80 percent. Page load times improve across the board, and the improvement is most noticeable on pages that rely heavily on dynamic content like product listings, account dashboards, and search results.
For WooCommerce stores, object caching means faster product pages, quicker cart updates, and smoother checkout experiences. For content-heavy sites, it means faster archive pages, category listings, and widget-heavy sidebars. For membership sites, it means logged-in users get fast, responsive pages rather than slow database-heavy loads on every click.
Google also factors page speed into its ranking algorithm. A faster site means better Core Web Vitals scores, which can directly contribute to improved search rankings. With object caching included on every FluxRunner plan, you get a performance advantage that many sites on competing platforms are paying a premium to access.
Object Cache vs Page Cache: What Is the Difference?
It is worth understanding how object caching differs from standard page caching, since both are common caching strategies for WordPress.
Page caching saves a fully rendered HTML version of a page and serves that static file to visitors instead of rebuilding the page from scratch each time. It is very effective for public-facing pages that do not change often and look the same for every visitor. Most WordPress caching plugins, like WP Rocket or W3 Total Cache, primarily focus on page caching.
Object caching works at a deeper level. It caches individual database query results, options, transients, and other computed data used by WordPress and its plugins. It is particularly useful for dynamic pages that cannot be fully cached as static HTML, such as cart pages, account pages, and pages that vary based on the user who is logged in.
In practice, the two types of caching work best together. Page caching handles the public-facing static content efficiently, while object caching handles the dynamic, database-heavy backend work. FluxRunner provides object caching as standard, giving you the foundation to layer other caching strategies on top.
Get Enterprise-Level Performance Without the Enterprise Price Tag
Object caching used to be a feature reserved for high-budget hosting plans or technical users who could set up their own Redis server. FluxRunner changes that by including it on every plan as a standard part of what managed WordPress hosting should be.
Whether you are running a personal blog, a growing WooCommerce store, or a high-traffic business website, you get the same performance infrastructure. No upgrade required. No add-on fees. No configuration needed.
If you are currently paying a competitor extra for object caching, or running a WordPress site without it at all, FluxRunner plans start from just $8 per month. That includes dedicated resources, object cache, multi-node redundancy across the decentralized Flux Network, and everything else you need to run a fast, reliable WordPress site.
