The website opens very slowly. Is there any way to increase the website opening

Hello,

1)

–Minimize main-thread work – I suggest using the Wp Rocket to fix it, more details are here: https://wp-rocket.me/google-core-web-vitals-wordpress/minimize-main-thread-work/

-Reduce JavaScript execution time – also the WP Rocket can help with it, check this: https://wp-rocket.me/google-core-web-vitals-wordpress/reduce-javascript-execution-time/

-Reduce the impact of third-party code – it looks like 3rd party plugins affect that – https://prnt.sc/n8Khcl-A9XVK

–Serve images in next-gen formats: Consider using a plugin or service that will automatically convert Ensure text remains visible during webfont load uploaded images to the optimal formats e.g ‘Imagify’ from the Image Optimization tab in ‘WP Rocket’ to convert your images to WebP.

-Avoid an excessive DOM size – The number of DOM elements are generated in the process of content building. All page builder elements are DOM elements. If you want to reduce DOM elements you will have to reduce the content: widgets, products, menu items, and others.

-Reduce unused JavaScript – Use the WP Rocket to fix that, navigate to WP Rocket -> Settings -> File optimization -> enable Minify JavaScript files: https://prnt.sc/gRnGNFDeaCCN and additionally these options: https://prnt.sc/fCMisMjViraZ

-Properly size images: the solution is described here – https://developer.chrome.com/docs/lighthouse/performance/uses-responsive-images/?utm_source=lighthouse&utm_medium=lr

-Serve static assets with an efficient cache policy – You should cache immutable static assets for a long time, such as a year or longer, so you need to configure your server to return the Cache-Control HTTP response header:

For now, it’s adjusted for 30d on your server – https://prnt.sc/7RGRdR_6P2OU. It should be 1year+ as in the example: https://developer.chrome.com/docs/lighthouse/performance/uses-long-cache-ttl/?utm_source=lighthouse&utm_medium=lr#how_to_cache_static_resources_using_http_caching

-Reduce unused CSS – To fix that, I suggest using the WP Rocket. WP Rocket -> Settings -> File optimization. Enable CSS minify and combine it: https://www.wpbeginner.com/wp-tutorials/how-to-remove-unused-css-in-wordpress-the-right-way/

2) The issue is in the size of the images, on our demo, the bigger image is 600×600 and the others as 300×300.

So you need to upload these https://prnt.sc/l43PYpj_frL- images with the same dimentions.

Kind Regards
