Do Plugins Slow Down WordPress Websites?

Do plugins slow down WordPress websites?

Plugin overload is one of the biggest issues that plague WordPress sites.

The reason plugins are so bad for speed, according to KissMetrics, is that they “add code to your pages that aren’t being used often enough to be cached by browsers”.

The more inactive plugins you have on your site, the longer it will take for new pages to load.

Since each plugin adds its own (usually significant) functionality and features, it is strongly advised to use as few plugins as possible.

At the same time, we also need to realize that there are many types of WordPress plugins:

Social sharing widgets, security suites, backup tools, contact forms… all of them are valuable for some websites, but can also worsen the user experience of others.

That’s why it would be a good idea to figure out a way to see which plugins are slowing your site down.

There are different plugin debugging tools available on the web, but some of them do not work properly for all hosts and servers, while others simply provide too many details.

If you want to get a quick and useful overview of your plugins, we recommend that you give the query monitor plugin a try.

The plugin has been around for years and it has gathered a significant number of positive reviews from both beginners and experienced users.

As stated on their Github page, this tool “monitors your MySQL queries in real-time”.

In other words, if you want to find which plugins are the most demanding when it comes to resources, this is the tool to use.

Easier than most other tools and plugins available online, Query Monitor lets you quickly see which requests are slowing your website down.

It is compatible with PHP and works right out of the box – no need for any configuration.

The plugin is designed with a simple and convenient drag-and-drop interface that allows you to filter your requests by hosts, URL paths, queries, status codes…

There are also several useful configuration options available, such as the ability to hide errors from certain plugins or themes.

In case you want to check how fast your site is without having to install any third-party plugins, we recommend using the free website speed test tool provided by gtmetrix, pagespeed insights or Pingdom.

These tools let you analyze and improve your site’s performance (load time) and provide detailed analysis of all aspects that impact your site’s speed – CDN usage, website uptime, mobile performance…

10 reasons to avoid slow plugins:

1. Slower loading time for pages.

2. Increased server load (frequent requests).

3. More complicated code (less efficient, more vulnerable to security issues).

4. Higher chances of downtime and errors.

5. Lowered SEO performance due to poorer site response times.

6. Decreased conversion rates and sales/leads.

7. Potentially annoyed visitors leading to higher bounce rates.

8. Higher chances of being blacklisted by search engines for spam/malicious activity.

9. Lower user productivity.

10. Lower the reputation and trust of your business.

In the end, what you should remember from this article is that plugins have a pretty high impact on your site’s speed and user experience.

For that reason, try to avoid overloading your website with unnecessary plugins even if they were previously useful for you.

Check regularly which requests are slowing down your site using a simple query monitor plugin.

If required, you can always switch to a plugin with fewer features and less demanding requests.
