By default, Wordpress won't load your inactive plugins when someone visits your website. However, will load all your active plugins and then depending on each plugin will load the required scripts and stylesheets as well.
Literally speaking, a really good plugin will try to only load when needed.
The problem? With so many features and user options, it's very difficult for plugin developers to guess whether you will need the given plugin or not in a certain moment. And obviously, they have no choice, but to load all the required files just in case.
Wich will affect your loading time and your site speed results. Especially on mobile devices. This is why there is a constant buzz out there regarding the number of your active plugins and their effect on your site speed. It's a hot and often misunderstood topic ... Not so long ago I published a short tutorial on this highly debated issue:
How to avoid using plugins that could affect your site and how many is too many
The truth is that many professional plugins (and themes) are providing simple and customization options that will allow you to disable (hide) given features on mobile devices. Still, that's a rare "best case scenario" ... and is really annoying to see all those poor mobile test results.
This is why I've created this short tutorial where I will show you how can you improve your mobile speed by disabling individual plugins for the mobile wersion of your Wordpress site.
Ready? Let's do this!
My mobile speed is horribly low. I am trying to follow your tutorial. I downloaded the plugin.
I do have the must use plugin organizer MU but the file is empty.
This is where I lost you.
Where do I go from here?
Thank you for your help in advance.

I know that when you give us training that it will be at least four pages. I liked it when you wrote: Ready? Let's do this!
I checked my site speed with Google and received a notice that my about me post didn't fit well for mobile. There wasn't enough spacing between paragraphs.
That was before I learned about constructing a readable page or post. However, I did try to solve some of the problems before I got that notice from Google.
I tried to copy it and paste into Word, but I couldn't overcome the font size ( bold ). I'll just have to try and do it again.
what are the most common plug ins you personally use on your main niche website, I feel 5 plug ins at times seem very restrictive for my website. which is what the site manger details suggest . I find their are so many plug ins such as the one you mentioned would be useful but then pushes the number of plug ins higher again.
Finding the magic number 5 really tough. love to see how you combat this?
