BerqWP Questions

So if a server already has LiteSpeed ​​​​​​and does not use the LiteSpeed ​​​​​​plugin, will it have better speed with BerqWP enabled❓
🤔
And if a server does not have LiteSpeed ​​​​​​at all, how much better will it have speed with BerqWP enabled vs without LiteSpeed ​​​❓
Have you done any tests❓
Do you have any comparison tables❓

Will there be no problem on a service that is already running on Nginx❓
Will it improve its performance even more if it is on Nginx❓
🤔

What elements other than images are included in the CDN?
Which elements are included in the CDN delivery, such as fonts, JS and CSS?

We are trying BerqWP and have been happy with the speed improvements.
However, our title fonts are not showing up properly after the pages are cached and we've been unable to figure out how to get them to show properly.
We had sent a question to BerqWP support but have not had a response yet.

Also, we use WPvivid's image optimization and even though we've selected Disabled Webp images, the images are still served by BerqWP's cache images, which causes the page to not load with images in older versions of Safari. What's the fix?

Thanks.
