Hello @rawny and thanks for your thoughts about Wordfence!
We’d love to help solve your issues but you haven’t asked for any help and forum rules prevent us from doing so in the reviews section. If you want help please post a question in the forums and our staff there can work with you to solve the issue. I checked and can’t find a support request from you.

I recently did a test with Wordfence being installed on multiple sites. I used web.dev, GTMetrix, and our own FastorSlow.com site speed tests and found some interesting results.
I found that sites with Wordfence installed were not seeing any difference in Performance, Accessibility, Best Practices, SEO, 1st Contentful Paint, Speed Index, Largest Contentful Paint, Time to Interactive, Total Blocking Time, Cumulative Layout Shift than without Wordfence.
You mentioned testing on 3 different servers, but I am curious about what sort of servers they are. If you’re seeing any sort of issues, we would like to take a look at what might be causing the problems in our support forum, which I had provided to you already.
Thanks again for your feedback! We appreciate it!
