There are a few categories of plugins that either duplicate functionality that WPhost already provides, or are known performance-killers on sites.
As a managed WordPress host, our goal is to make sure you’re starting out with a site that just works.
WPhost already has you covered on the backup front. We back up every site each and every night on external servers. Backup plugins, on the other hand, can be incredibly resource-hungry. When running, they can take a big bite out of the resources you need to deliver content to your visitors, which could slow your site down at an inopportune time. For larger sites, some of the MySQL queries can even take your site offline. These plugins also often store large backup files on your server, which can unnecessarily fill up your disk space. However, if an extra backup is what you need:
WPhost handles caching at the server level, eliminating the need for caching plugins. Server-side caching is significantly more efficient and scalable than any plugin-based caching, as it doesn’t rely on PHP at all. This aside, caching plugins run the risk of interfering with the caching we already have in place.
For users who want to use WP Rocket, that plugin will need to create something called a persistent cache. The WP Rocket plugin will effectively dictate that the cache should never get rebuilt unless this plugin explicitly tells it to. In order to hand over control to WP Rocket, we need to enable a feature called WP_CACHE. Just open a support ticket to enable this for your site.
WPhost servers are configured specifically with WordPress security best practices. We help prevent brute force attacks, lock down core WordPress files (including xmlrpc.php), and take many other security measures for you. In many cases, security plugins can slow down sites by over-utilising server resources, interfering with our caching, bloat the site’s database, and/or interfere with our native security software.
Related Post Plugins
In general, if you aren’t manually assigning related posts, any plugin that is automatically showing related posts is going to be doing so via a barrage of MySQL queries that happen on each and every page load. The end result is often a devastating hit on your site’s performance and substantial damage to your database.
Link Checker Plugins
Like some of the other listed plugin categories here, the ongoing jobs run by these plugins can be really taxing on your server and steal resources that your visitors need to view your site in a timely fashion.
