If you have ever touched upon the subject of WordPress in the it crowd, must have been someone who argued that it is not necessary to install many plugins on WordPress. Obviously, the more plugins you put the more it starts to slow down WordPress, isn’t it?
But is it really?
In this post we will try to figure out whether a lot of installed plugins affects the speed of WordPress. So if your admin panel is also bursting with tabs installed plugins, continue reading.
A lot of the plugins installed is always bad?
Let me just clarify, I’m not a developer, but have sufficient experience in working with WordPress, to say that there is nothing wrong with that your site has a lot of plugins. With some reservations.
One Pippin Williamson, the author of the projecttold that some of his site is over 80 plugins! And this guy definitely knows a lot about WordPress and all the subtleties of his work.
In an ideal world where ideal developers ideal basic plugins of the highest quality standards, you can install as many plugins as you allow it to accommodate the disk storage on your hosting.
But there is one problem…
We do not live in a perfect world. We live in a time when a day has hundreds of new plugins, but after six months most of them stop updating for various reasons. And more recently, some popular plug-ins have gradually become abandoned pieces of code resembling this:
You get the idea? Any plugin with excellent optimization and clean code after 2 years without updates is turning into a potential threat.
Different plugins have different influence on job site
There is another feature which does not allow to say with confidence “you should always be not more than 30 active plugins”.
See, you can have 30 plugins that make minor changes in the work of WordPress, and all in all, these plug-ins will have zero impact on the performance of your website.
And at the same time you can have 1 “heavy” plugin that does a lot of unnecessary queries to the Database and slows down your entire website. In the end, the 1 the plugin will have a greater effect on the work site than the other 30 combined.
The basic idea here is this — you should never judge about the impact on the operation of the site according to the number of installed plug-ins.
Think about it: how can you compare the WooCommerce plugin with the plugin “Disable Emojis”? The first is a e-Commerce system, a huge superstructure with a bunch of code. And the second just removes one line of code from your site and disable the emoticons.
What could be the problem if you have a lot of plugins?
OK, let’s not talk about the ideal world and look at things from a realistic point of view. Because people can start real problems with the website, if you tell them that you can put as many plugins without thinking about anything.
These problems do not depend directly on the number of installed plug-ins, but rather purchased the inexperience of those people who put everything without thinking.
1. The speed of the website
If you install plugins, heavily-loaded CPU of your hosting server or making too many HTTP requests and database queries, it 100% will affect website performance.
If you install plugins that add files to the queue a bunch of my JS scripts and CSS styles, this will also slow down your website.
Install enough of these plugins, and your website to turn into a white screen with an error 503 (Service Temporarily Unavailable).
2. Security and vulnerability
This issue may have far more serious consequences. Vulnerabilities in plug — ins- the main weapon of the hackers, and is almost a guarantee that the site will be hacked.
According to, only 3 of the plugin (often included with kit with premium themes on Themeforest), massive hacking of WordPress websites.
Havealso has its own impressive list of “leaky” plugins…
So, we can say that with every new installation of an unknown plugin, you buy a lottery ticket problems and vulnerabilities. And the more tickets you bought, the greater your chances.
3. Incompatibility between plugins
A well known problem: installed a new plug — in no longer functions correctly other, already established earlier.
The more plugins installed, the greater the likelihood of internal conflicts between plugins.
4. Hell admin
Have you ever worked in the admin of WordPress where the sidebar menu with all the installed plugins you have to scroll 2 screens down? It’s a nightmare!
Don’t know, maybe it’s perfectionism, but working with the WordPress dashboard is much nicer and more comfortable when she’s not bursting with additional sections and menu from all installed plugins.
Good thing there are plugins like Admin Menu Tweakerwhich can hide the extra menu items in the admin area.
And what’s the solution?
Every time you install a new plugin what this plugin does and how it can affect your website. If this plugin:
- creates a lot of HTTP requests
- creates many calls to the Database
- CPU your WordPress hosting
— then think twice before installing it. Because these plugins slow down the speed and responsiveness of your website and affect your ranking in Google.
There is a plugin Broken Link Checker, which people set up immediately without hesitation. And in vain. This plugin belongs to the category plugin, pretty intensive Database.
On the other hand, there are many plugins that simply add some static serving code for small edits of the website. With these plugins your website will not slow down.
But again, don’t forget to look at the date of the last update of each plugin!
To determine which plug has on the site the greatest impact and load, you can install:
And you can easily do and check manually. Just disable all plugins and enable it back one by one, each time checking the performance of the website.
You can also try to track down what is causing load when you open Chrome Developer Tools and carefully study the picture on the “Network” tab.
So what is the result? Can I install WordPress many plugins?
You can, if you know what each plugin does and what kind of load the website it has. You should be aware of all the risks.
Otherwise, you can amass a problem, because with the increase in the number of plugins increases the chance of getting the conflict of incompatibility between them and increasing the potential threat to the security of the site.
A lot of plugins — is how much?
Here are all individually and depends on the “severity” of each plugin, and on the technical characteristics of your WordPress hosting. For normal shared hosting may be sufficient and 10 plugins that will load the Database for its number of hits and put the website.
At the same time, if you have a VPS with enough resources you can experiment and install as many plugins as you want.
