W3 Total Cache is the mother of all caching plugins. It has a lot of functionality in a single plugin, which improve your website performance and user experience.

Recommended W3TC Settings for Shared Hosting

If W3-Total Cache is your cup of tea, use with extreme caution, especially if your website hosted on a shared server. The shared servers do have rules against using too many resources. On the Shared hosting environment, you’re probably sharing your server with several hundred people, you have no ability to use more options because of the limitations of the hosting provider.

The best lightweight caching options for websites on shared hosting.

  • Page Cache
  • Browser Cache
  • CloudFlare 
  • Leave Minify, Database and object caching disabled

Because, not all servers provide optimized results with Minify, Database and object caching settings. Minify has a high possibility of crashing your themes and plugins. However Database and object caching are resource intensive and can sometimes cause speed related issues for sites. Some web hosting companies likehostgator recommends disable Object Cache and Database Cache since it imposes a lot of load on their server for no real benefit. Before you start, ask your hosting provider what cache settings you must use, just to be on safe side. If they allow you to do so, go ahead and take advantage of these options, because it ought to help speed up your website a bit.

  • Make sure the preview mode is disabled.

Page cache

The page cache is the biggest performance boost. It decreases the response time of your website.

  • “Enable” Page cache.
  • Page cache method: “Disk: Enhanced”


Minify reduce load time by decreasing the size and number of static files (such as CSS and JS files).

However, minify has a high possibility of crashing your themes and plugins, we recommend disabling minify and use cloudfare’s minification instead (which would be safe, setup is amazingly painless & no crashes).

Database cache

If you are on a shared hosting, Database cache will slow down your site instead of making it faster. It is effective only for VPS / Dedicated hosting.

Object caching

Object caching is generally not recommended for Shared hosting.

Browser caching

It helps in leveraging browser caching, thereby increase your Google page speed score.


  • CDN (Content Delivery Network) is not a free service. Leave this disabled.

Network Performance by Cloudfare

W3TC includes built-in integration with Cloudflare functions for speed optimization. CloudFlare is a website optimization service which will cache some of your website content to servers around the world, which helps promote speed, stability, and protection for your sites. 

To utilize this service, you will need to sign up for CloudFlare account, where you will get API key to integrate with your WordPress website.

Note: Do not use more than one minify option on your site (for example, don’t use CloudFlare’s minification and minify plugin at the same time). A conflict will eventually arise. If you’re already minifying on your site, then definitively turn off CloudFlare’s Minification as well.

If you want to see your Google Page Speed report on your WordPress dashboard, enable this option.
