PHP rfc preload in PHP 7.4

Going to deep dive a little on a server.
When I was reading here PHP: rfc:preload and I read it was merged into 7.4

---

So testing it now on my "private testing server" with the PHP 7.4.0RC2 that has been released on 19 September

 

It's updating...... .. For a test server I did not go for a costly one

Oh, no it's done...

Not bad for first day testing: 63 requests

 

I don't recall exactly, but I guess it was around 1100ms. Won't touch it now. It's perfect. Can't wait until November.
All last request are images. They come in a little slower. (as you can see in the image the first with 21ms)
EDIT: I use the http2-push-content wp plugin. Helps a bit
