Im testing this site to see how i can make it better. Ive been trying to use GTMetrix to see some specific data points but it receives a 403 error. this site is on a server with multiple others and this is the only one with this issue currently. It is using AIO WP Security

One solution I found to not remove this plugin and continue with the optimizations was to remove the non-critical js rendering through functions.php with the following function:

//remove render blocking from non-critical js
//- unless it is within the WordPress administration interface
//- and except cart_page

function defer_parsing_of_js ( $url ) {

     if ( is_admin() ) return $url;

     if ( is_cart () ) return $url;

     if ( FALSE === strpos( $url, '.js' ) ) return $url;

     if ( strpos( $url, 'jquery.js' ) ) return $url;

     return "$url' defer ";

}

add_filter( 'clean_url', 'defer_parsing_of_js', 11, 1 );

you did a great job! i’m testing the plugin for a view hours now. i activate the trial version. one thing is confusing: gtmetrix and als google lighthouse still tells me to use correct image sizes. this is one most annoying thing in speed optimization. please have a look here: https://dev.filmartwear.com/shop/t-shirt-the-end/

everything works fine, the cdn delivers the webp and srcset is set. do i have to get rid of the width and hight attributes of the img tag? what do i have to do that gtmetrix and google don’t complain about it anymore

thanks, kay

I’ve put the website through GTMetrix and it’s bringing back “Avoid an excessive DOM size” and it’s the Instagram feed on the site it is highlighting.

Is there anything we can do to improve this as this will improve the overall grade the site will be given?

I love your plugin. Unfortunatly I have an issue. When i run a GTmetrix analysis i get the error: failed (err_name_not_resolved). If i run a pagespeed analysis I have opportunities to reduce css and JS regarding Jetpack boost. How can I solve this?

Another issue. Since last update when i do a pagespeed analysis I get the error “Preload Largest Contentful Paint image”. This didn’t happen before.

Thanks

I was using WP Rocket until a few days ago and switched over to Litespeed 3 days ago.

On GTMetrix, my site shows LCP of 4.1s and Performance as 55%, Grade D

whereas with WP Rocket , I always achieved Grade A, Performance 95-100% and LCP of about 150ms.

I want to stay with Litespeed and need your help to make my site score as close to what i was achieving earlier.

I just read one of your replies to someone from 2 years ago & did the setting for crawler too.

Let me know if you can help me resolve

Thanks
