Hello @liathess ,
I am very sorry to hear about your GTmetrix score. I don’t know why you conclude it is from Gutentor. Optimization does not depend on a single plugin. It depends on various factors on your site.
Our site Gutentor.com created with Gutentor, not using any premium caching plugin but you can see a very good GTmetrix score.

Probably you are missing something on your optimization settings.
Best Regards!
Hi, i conclude because it only happens on the frontpage -not on single posts-, which i built with Gutentor. My optimization settings also didn’t change at all, after i switched from Gutenberg built layout to Gutentor.
As i see from your screenshot, you are testing a static webpage, with a minimal load and not a posts feature. My webpage is news related, so when it has to load many posts on the frontpage, the speed drops dramatically. I also used only 4 sections with posts, which is not considered huge load for a news website, but it went so slow, i had to drop the plugin.
Anyway, as i said i like this plugin features, wish you the best.
Hello @liathess ,
I appreciate your review and rating. It is strange using the cache plugin not increasing your site score.
Here are the test results of News/Magazine and WooCommerce.
1. News and Magazine
GTmetrix score

2. WooCommerce
GTmetrix score

Note: not using any premium plugin
Anyway, we are continuously improving the Gutentor according to our user feedback. We will look into your points too. I am happy to know you like the plugin features.
Best Regards!
