Thank you for your quick answer !
In incognito mode, the pages are very fast, and I have great results with tools like PageSpeed or GTMetrix. That’s why I’d like to keep you plugin !
I just tried what you said (adding the query string /?wpacu_no_load), and there’s a huge difference indeed. It’s 10x slower without the query string when I’m logged on any page. If I add the query string, it’s loading at a normal speed.
I’m sending you my System info on you contact page.
Thank you !
