Hello! The website on the virtual world. hosting from Beget. Decided to switch to HTTP/2, since the multiplexing, speed and everything. Certificate of Let's Encrypt, outputs, and connects it Beget, without our participation, just click "Install certificate" in the PU.
After the transition to the new Protocol via a secure connection when you first load the site became a very long time to load, slower 3 times than before. In .htaccess removed the redirect, to see the difference. Tested on different devices, with different Internet connections with different providers. Everywhere the same story.
Plagued support about this, but in addition to bringing screenshots and "we are all loaded equally well" is not heard.
The link to the site: stroi-ka.org
I hope you will be able to help. Thank you!
