Speed issues - are there any configs within zero trust which can affect the speed?

What is the name of the domain?

What is the issue you’re encountering

I am geting slower speeds via the tunnel vs. LAN even though my bandwidth is fine

What steps have you taken to resolve the issue?

Ive tested the same service via local LAN vs. using the HTTPS zero tunnel.
My internet upload bandwidth is high enough to achieve faster than 1.5MB/s upload (it should be around 10MB/s).
I use the same service via local IP /w port and it achieve the maximum speed of 10MB/s with my cat4 cable so thats correct.

Im using Unraid-Cloudflared-Tunnel

I tested it with my DDNS and port-forward and that method is achieving the maximum speed.
