The amount of code you have on any website decides whether a website will load slowly or fastly.
How do Plugins make a Website Load Slow?
When you have 5-10 or even 20 plugins activated on your website to work, they all take time to load together on the visitor’s browser which increases load time. Hence, eventually decreasing the site speed.

Factors of Plugins responsible for Slowing Down Websites
1. Website Coding
Code is programming in web development to build websites that gives the website’s design, instructions, and features. This code is downloaded by every visitor who loads the website in his/her browser.
And the less code a website has determines the speed of the website to load in a person’s browser.
2. Heavy CSS Files Used
Cascading Style Sheet(CSS) is used to style a website with HTML programming. It helps in styling the presentation, background color, icons, fonts, font sizes, layouts, etc.
This is the most fundamental thing in web development.
But the problem is that some of the unused CSS files increase load speed as they are in your website layout and are of no use generally.
4. Plugins Extra Database
Some Plugins with complex actions and code makes the backend processing hard for the browsers to load the websites. There are some quickly loading plugins that have a negligible effect on the load speed but even one complex plugin can increase a site load speed by one second.
So one should inspect a plugin before installing it that does it have a high effect on load speed or not.
5. External API’s
An external or open API is an API designed for access by a larger population as well as web developers. This implies that an external API can be easily used by developers inside the organization (that published the API) and any other developer from the outside who desires to register into the interface. (By RapiDapi)
In general, calling an API is more time-consuming than calling a user function due to Context switching (called Context Switching Time) which is not best for developer use. This is the time required to save the context of one process that is in the running state and then get the context of another process that is about to come in the running state.
