enabling tls/ssl causes significant drop in performance

Description
Downloaded the latest release which has the tls option and set up speedtest-go using tls/http2 using Letsencrypt certificates. This caused the download speeds to drop to approx. 66% and upload speeds to as low as 30%, compared to non-tls settings.
Server
Running on a LXC Rocky 8.6 Linux install
Client
Firefox 102.01 on macOS Monteray
Steps to reproduce
- install latest release
- activate tls/http2
Expected behaviour
Expected mostly the same up- and download speeds over tls or plain
Screenshots
Added screenshots for wired and wireless tests. Lefts ones are without tls, right ones with tls/http2 enabled. Top ones are wired connections, bottom ones are on wireless.
HTTP2 Multiplexing mux multi http connection to one connection. Thus, speedtest result will always same as a single connection test result.
some technique to solve this, like use different domain, such as cdn1.example.com,cdn2.example.com,cdn2.example.com
browser treat them as different host despite their A record points to same host. therefore browser can make multi connection to same host
