Probably more than once you have had, or will have situations where your website will not be able to boast good quality and performance results. Everyone without exception encounters this problem sooner or later. We have it like in the bank 🙂 .

WordPress does not natively offer any caching mechanisms, so we can either rely on what the hostingFor example, nginx cache plus database object caching (Redis, Memcached), but this is usually not enough. So you need to reach for other tools.

Cache plugins for WordPress

There are countless of them. If you type the word "cache" into the WordPress repository you will find many plugins to help speed up your site.

Cache plugins in the WordPress repository

What you see above are just the first 12 results. There are many more. With so many extensions, however, a problem arises. Which one to choose!

My suggestion. Test as much as you can, experiment with the configuration and in this way you will step by step emerge the plugin that does the best job of optimizing your project.

There is no such thing as a universal plugin, or as in the title of this article the best cache plugin. On one site WP Fastest Cache will work great, on another W3 Total Cache or LiteSpeed Cache, although the latter will only work on LiteSpeed hosting.

Which cache plug-in do I consider the best

I mentioned above that there's no such thing as "the best cache plugin", because depending on the configuration of your site, depending on what plugins and theme you use, it's not necessarily always the same plugin that will do the best job.

However, if based on my experience, and I have used most of these plugins, I would point to one that gives the best results in my projects and is also easy to configure, I would point to the following plugin WPRocket.

Configuration comfort

This is an important issue, especially if you don't have much experience yet. When you want to use, for example, LiteSpeed Cache in such a situation, it may not be feasible to implement the configuration properly. This plugin is a real powerhouse with a huge number of settings. Its correct configuration requires knowledge of the subject and a lot of experimentation.

Very often my students opt for this plug-in and then I see that they cannot configure it. You have to be aware that there is no universal configuration in this case either. On one website configuration X will work, on another it will generate problems and you need to use configuration Y. It is not always an easy task.

Of course, there are plugins in the repository that are geared towards simplicity, such as the WP Fastest Cache extension mentioned above, or another not yet mentioned: Cache Enabler.

Unfortunately, practically all plugins available for free (except LiteSpeed) have limited possibilities and only PRO versions (paid) extend these possibilities.

Why WPRocket

Before I write about why I think this plugin is the best, I have to write that it is not available in the WordPress repository. There is only a PRO version available, but if you want to actually optimise your site well, you can't do without investing in one or another PRO plugin anyway. Operating on the free version usually brings only half an effect, and you should care a lot about making your website as efficient as possible.

The plug-in is easy to configure

It will not take you too long to configure it properly. The interface is very clear and decently polished.

Cache works immediately after activation

Most plugins require you to go into the settings and enable the caching mechanism after installation and activation. WPRocket after activation has the caching mechanism active right away. The only thing left to do is possibly configure file optimization, media or preload, which is also not particularly challenging.

Simple file optimisation

Just because it's simple doesn't mean it's less effective. You have everything you need: minification, merging files so the site generates less work for the server, and the ability to generate critical CSS, a mechanism that tries to create a CSS file that contains the sheets actually used. It may not be perfect, but in the case of WPRocket it works pretty well.

Lazy media loading, embedding....

It is worth using these options as they can make a significant difference to quality results and page load speed. Configuring these parameters in WPRocket is trivial.

Preload based on the site map

The cache builds itself cache data when the page is called, e.g. someone opens the page. As a result, the first input takes a bit longer, because the cache is created at that time, and this is a more demanding process. However, the next input dumps the data already from memory. The number of operations and the time needed to perform them is significantly reduced.

Preload is designed to automatically create a cache for your page. It works just like a crawler, which is a robot that visits the page. It opens each page/subpage in order to load it into memory, so it does not have to be done by your visitors.

WPRocket allows you to run the robot based on a site map, which usually shortens the whole process and thus generates less CPU usage.

The best cache plug-in should have a mechanism for preloading pages into cache

Google Analytics or Facebook Pixel

For most external scripts, including those from Google or Facebook, their implementation causes a deterioration in the performance results of the website. These are not always drastic drops, but they are there.

WPRocket allows you to activate a one-click function that causes these external scripts to be loaded from your local server, making them run faster.

Database optimisation

Very often we forget this, but it's worthwhile every now and then to get rid of unnecessary ballast from the WordPress database that causes some SQL queries to take longer to execute than they should.

WP Rocket gives you control over this area of optimisation with an option to automate this process.

Cleaning the database

Yes, yes. I know that there are plugins to optimise the database, but I also know and repeat it like a mantra that the fewer plugins you install the better for your site.

Other functions

I won't go into any more detail about them, but it's worth knowing that they are there. You can control the heartbeat of your WordPress site, and therefore change the frequency of API calls, which by default are made every minute. By modifying the frequency to every two minutes for example, you can save a lot of computing resources, which with larger projects will be visible translating into improved site performance.

If you use a CDN such as BunnyNET (recommended), then you can use WPRocket to set up host/hosts for different file types (CSS, JS, images). WPRocket also has its own CDN that you can use for an additional fee.

There is an automatic graphics optimisation service offered for a fee by WPRocket, although in my case BunnyNET does a better job at this.

Effectiveness of CAPocket

Configurations, configurations, but a plugin is mainly supposed to optimise and increase the speed of a website. How does WPRocket perform in this area?

I use this plugin on all my sites today and without exception. Not because I have such a whim, but because WPRocket allows me to generate the best results compared to other solutions I have had the pleasure to experiment with.

The plugin is not expensive, and it really works superbly. Anyway, if you search the web for rankings on cache plugins, assuming they are not sponsored rankings, in most cases it is WPRocket that is listed first. And for good reason 🙂 .
