First of all let’s talk about what causes the wordpress having slow performance?
WordPress is the CMS (Content Management System) based on PHP and MySQL. It is reportedly the most popular website management or blogging system.
By default wordpress is completely optimized and Google-Friendly but the problem starts when we begin working on our website, downloading themes, third party plugins and uploading images which are not flexible for our website.
There are some main reason making our website have slow response time.
Images: When we upload an image for example a product image, and the product image size by default is 450 x 450 pixel and we add an image of 450 x 550 pixel, in this case the CSS and JavaScript files from the theme which we are using will resize our images on the fly and it takes time to resize and load the image and also images with huge size (250 kb +) will cause our website performer slow.
How to find the exact size of any image uses in WordPress theme?
To find the image size I recommend Google chrome developer tools simply right click on your web page and click on inspect and then click in the image you want to know the size and the image size will be displayed.
Unused JavaScript and CSS files.
Removing unused JavaScript and css files is a critical issue and also in some themes with animations and sliders there are some unnecessary JavaScript files that loads and causes our website to have a slow performance and we can find a lot of plugins that help us fix this problem but the plugins will cause our website break and some of the functionally of the website will not work properly.
