Performance and Speed of a Website

[j.silver]

Hi all,

 

How is the performance and speed compare between a website that is coded with html 5, CSS 3, MySQL, and PHP 7 only and the same website but added to it js, jQuery, and JSON?

adding anything will obviously impact performance, it's just to what degree and at what overhead. Every file from the server to your browser an HTTP request and of course the size of each payload will incur a cost, and then there's the cost to the browser to evaluate and execute it. That said, you could have problems with a slow SQL query, which could make the site slow and have nothing to do with JavaScript, so it's really all in how well you know the technologies and how you apply them to your application. Then, when there is a problem, it's about knowing how to use profilers, networking tools, and debuggers to identify and solve it.
