Why don’t we take a better look underneath the hood?

Optimizing Your Basic Settings

Like most WordPress bloggers, the “Basic Settings” page might be the primary part you’ll verify.

Luckily, that’s additionally where W3 Complete Cache’s core options may be enabled, specifically:

If your website at present runs on a shared host, select ‘Disk: Enhanced’ as your web page cache technique. 

‘Opcode’ caching, nevertheless, have to be chosen in the event you improve to a dedicated server. For many who use cloud internet hosting, then ‘Memcached’ must be your page cache technique.

2. Minifying Your Code for Lower Bandwidth Utilization

Code minification is another W3 Complete Cache function that would give your website’s performance a simple increase.

Understand that your website’s codesconsume bandwidth to be loaded into net browsers. This consists of CSS, HTML, JavaScript, and so on. 

The larger these bits of codes are, the extra bandwidth they have to be transferred.

In turn, this increases the general loading time of your page.

Easy methods to do minification the old-school approach

With minification, unnecessary code parts like feedback, whitespaces, and line breaks are stripped removed. 

Need to do it manually? 

Positive, for those who’re ready to stare in front of your pc for days or even weeks on end.

As an alternative, use a software like Minify Code to mechanically minify any code you upload. 

Minify Code

If that’s not straightforward enough for you, W3 Complete Cache can minify your codes in a snap. 

Doing it with W3 Complete Cache

On the “Minify” part, tick the ‘Allow’ checkbox and save your modifications. As for the rest of the settings, you possibly can depart them to their default values. 

Minify Page Cache Settings

Minification by means of W3 Complete Cache, nevertheless, might be disabled should you use Cloudflare. It’s an internet optimization and safety providers firm that implements code minification in your behalf.  

In the event you’re serious about Cloudflare, I’m pleased to inform you that they do supply a free answer. 

This allows you to benefit from a worldwide CDN, primary DDoS safety, and a free SSL certificate. 

Cloudflare Plans and Pricing

3. Utilizing Other Website Caching Methods 

Aside from the essential page cache mentioned above, you may also modify numerous caching options on the overall settings web page. This consists of database caching, Opcode caching, object caching, and browser caching. 

These caching options might be discovered immediately under the minify part.

Additional Site Caching Methods

Under are the precise methods to use each caching choice:

  • Opcode Cache — Opcode caching works by decreasing PHP code blocks in your web site. It’s solely out there when you have W3 Complete Cache Pro.
  • Database Cache — For those who use virtual internet hosting or a Content material Delivery Community, it’s greatest to go away database caching disabled. You might also need to check your website’s velocity after enabling this feature to see whether or not it helps. 
  • Object Cache — Whereas it might decelerate your WordPress admin space, object caching is advisable for dynamic web sites. These are sites that permit customers change or add content material, comparable to discussion board posts, purchasing carts, and other customizable parts. 
  • Browser Cache —Out of all of the caching choices, browser caching is the one you need to allow it doesn’t matter what. It makes use of the assets of your guests’ computers, so it gained’t negatively have an effect on your website underneath normal circumstances.

four. Updating Your CDN Settings

Following the extra caching settings is the “CDN” section. 

In simple phrases, a CDN works by leveraging a community of proxy servers distributed across multiple areas. Latency is then significantly lowered by letting customers obtain your website’s knowledge from the closest server. 

To a degree, CDNs also supply safety towards DDoS or Distributed Denial of Service assaults. 

So…does that imply W3 Complete Cache will give me a CDN?

Sadly, enabling the CDN choice on W3 Complete Cache doesn’t imply you’ll routinely obtain these advantages.

W3 Total Cache General CDN Settings

The factor is, a CDN can solely be utilized with the help of third-party providers. Aside from Cloudflare, other examples of corporations that provide CDN providers are: 

  • MaxCDN
  • KeyCDN
  • Rackspace

You’ll be able to view extra options by studying this listing of free CDN providers for WordPress blogs. 

When you use a CDN, then you must click on ‘Allow’ on W3 Complete Cache’s basic settings page. 

You then have to choose the appropriate “CDN Sort” from the drop-down menu to match your CDN provider.

Finding Your CDN

What’s that — you possibly can’t find your CDN from the listing?

Because of the recognition of W3 Complete Cache, your CDN provider can most likely help you in the configuration process.

Cloudflare users, for example, need to use the official extension in an effort to use W3 Complete Cache with their CDN. 

Cloudflare W3 Total Cache Extension

For different CDN service providers, the “Generic Mirror” choice will more than likely be used.

In any case, further setup is important when establishing your CDN with W3 Complete Cache. We’ll explore this process later with somewhat extra element.

5. Understanding Additional Settings

One of the explanation why W3 Complete Cache is so common is its comprehensiveness. 

In addition to the settings outlined above, it additionally has advanced instruments that take efficiency optimization to the subsequent degree. 

Granted, nearly all of WordPress users don’t have to play with these features. 

But in case you do, then let me gloss over those options actual quick. 

Reverse Proxy

Right after the CDN section, you’ll find “Reverse Proxy.”

This can be a function that refreshes the Varnish cache each time website content material is updated. 

If these phrases are unfamiliar to you, likelihood is you don’t need to make use of them but. 

Varnish Cache is an software accelerator that mainly utilized by giant sites and APIs. Once put in in your server, it independently performs caching on your web site’s content material for enormous velocity boosts. 

W3 Complete Cache’s reverse proxy settings allow you to specify your Varnish IP addresses. You then need to click ‘Save all settings’ in your modifications to take effect. 

Reverse Proxy Settings

To put things in perspective, Varnish is used by very giant websites like Reddit, Wikipedia,and Stack Overflow.

Until you get as much visitors as these websites, I wouldn’t worry about Varnish or reverse proxy settings for now.


Just like reverse proxy, the “Monitoring” part is one other function that the majority W3 Complete Cache users ignore.  

Principally, it permits you to monitor the performance of your website or net software by means of New Relic — a software program analytics service. 

For those who use New Relic, then you must configure your API key here.

Fragment Cache

For web sites that use dynamic blocks of PHP code, then fragment caching should give your web site a noticeable velocity improvement. 

As efficient as fragment caching is, there are two downsides to this function.

First, implementing it may be tough.

The “Fragment Cache” part of W3 Complete Cache’s common settings web page will assist with the first step of deployment. 

After you choose a fragment cache technique, you also need to define “fragment teams” in your PHP codes. This can be a process for a developer, however if you want to study, start with this page from W3 Edge.

Fragment Cache Method

Apart from the difficult configuration course of, fragment caching also requires you to buy W3 Complete Cache Professional.

This takes us to the subsequent function you need to find out about.


In case you have upgraded to W3 Complete Cache Pro, you possibly can enter your key on the “Licensing” section. When executed, click on ‘Confirm license key’ to activate your copy in your current WordPress installation. 

Where to Put Your License Key

That reminds me, we haven’t talked about the benefits of W3 Complete Cache Professional yet. 

We’ve already coated fragment caching, which is likely one of the 4 promoting points of W3 Complete Cache Professional:

Benefits of W3 Total Cache Pro

Miscellaneous Settings

W3 Complete Cache’s flexibility is in full show with the “Miscellaneous” part on the overall settings web page. 

At the very prime is the ‘Allow Google Web page Velocity Dashboard Widget’ choice. 

When correctly configured, it will present knowledge out of your web site’s PageSpeed Insights report on your WordPress dashboard. You merely want to pick the checkbox and enter your PageSpeed API key. 

Enable Google PageSpeed Insights on Dashboard

Utilizing PageSpeed Insights is a go-to technique of measuring an internet site’s efficiency. 

With the function above, it’s easier to tweak W3 Complete Cache since your velocity score is up to date in real time. 

When you don’t know where to get your PageSpeed Insights API key, check with this documentation from Google. 

With PageSpeed Insights integrated, you might also enable the ‘Present web page score in admin bar’ choice. It will make your web site’s velocity score instantly visible in your WordPress dashboard.

Under the settings associated to PageSpeed Insights is the ‘Verify rewrite guidelines’ choice.

As the description implies, it’ll provide you with a warning each time your rewrite rules have issues in your .htaccess file.  

Verify Rewrite Rules Option

Enabling this feature won’t have any uncomfortable side effects in your web site’s performance, so it’s greatest to go away it on. It will aid you keep the integrity of your website’s code. 

Shifting on, the ‘Allow file locking’ choice prevents multiple customers or processes to entry the identical file concurrently.  

W3 Complete Cache recommends protecting this feature disabled for NFS techniques along with web sites operating on shared internet hosting. 

Enable File Locking

Maybe the only state of affairs the place file locking is beneficial is on very busy websites the place entry conflicts are plausible. Even then, it might not end in any perceptible efficiency good points. 

Speaking of tentative performance optimization options, the subsequent choice additionally doesn’t assure improved loading velocity. Apparently, it has the precise reverse use case as file locking. 

In case your net host is NFS-based, think about enabling ‘Optimize disk enhanced page and minify disk caching for NFS.’ This could result in an honest improve in web site performance, but you’ll need to see for yourself if it works. 

Optimize Disk Enhanced Page

Lastly, the final two miscellaneous settings have nothing to do with web site efficiency improvement. 

With ‘Anonymously monitor usage to improve product quality’ enabled, you grant W3 Complete Cache to trace your plugin utilization. Helpful for those who care concerning the plugin’s improvement, however plenty of bloggers would like this to be off.

‘Allow caching statistics,’ then again, might be helpful for those who’re into fine-tuning W3 Complete Cache over time. 

Additional Miscellaneous Settings

6. Debugging Settings  

For those who plan to make use of caching statistics, it is sensible so that you can use debugging settings as nicely. 

Debug modes will generate in-depth information about certain caches when enabled. To use them, tick the checkbox of the mode you need to activate. 

W3TC Debugging Settings

The catch is, enabling any debug mode might end in less-than-ideal performance. That’s because your website has to put in additional work to trace W3 Complete Cache features. 

That stated, debugging ought to be achieved on a short-term foundation and disabled once you’ve worked out all the problems.

7. Importing and Exporting W3 Complete Cache Configurations

W3 Complete Cache is usually seen as a plug-and-play answer that takes little to no setup. 

With what you’ve read thus far, can you continue to say the same thing?

In all probability not. 

In reality, configuring W3 Complete Cache might take hours if you would like it tailor-made to your website’s needs. 

That’s why W3 Complete Cache lets you export and import plugin configuration settings. 

To import plugin configuration from an outdoor source, click ‘Select File,’ discover the HTML or .json document, and click on ‘Add.’ Consider it or not, there are literally WordPress blogs on the market that can help you obtain their plugin configuration. 

Import and Export Settings

In any other case, you must already know what to do subsequent: 

Aliases Field

10. Utilizing Cache Preloading

Let me guess — you’re nowhere close to doing something of that magnitude. 

During which case, it’s greatest to go away the REST API caching with the default setting: ‘Don’t cache.’
