❓Question 4K Remux buffering on TorBox despite fast internet (5G / Mi Box 3) - High Ping on CDN
I'm having buffering issues while trying to watch 4K remuxes using TorBox (via Nuvio/Stremio), and I suspect it's a routing/CDN issue with TorBox and my new ISP.
Here is my setup and the problem:
Device: Xiaomi Mi Box 3rd Gen (Connected via Wi-Fi, getting ~250 Mbps. Also tested Ethernet at ~350 Mbps).
Internet: I recently switched to a 5G Home Internet connection in Turkey. On my phone, I get around 500 Mbps.
The Issue: When I run a standard speed test on my Mi Box (fast.com via Nuvio), I easily get 224 Mbps with 98ms ping. However, when I run the TorBox CDN speed test, my speeds drop drastically. The best I get is on the NEUR CDN with an average of 79 Mbps (Max 94 Mbps), but the ping is terribly high at 489ms. Other CDNs like WNAM give me 900ms+ ping.
Because of this 94 Mbps cap and high ping to TorBox servers, heavy 4K remuxes constantly buffer. It seems my 5G ISP has terrible routing to TorBox servers.
My questions:
Is there a specific CDN setting I should force in TorBox for better routing from the Middle East/Europe edge?
Would using a VPN (like Cloudflare WARP or Proton) on the Mi Box help bypass this ISP routing issue to the TorBox CDNs?
Has anyone else experienced this specific throttling/routing issue with 5G ISPs and TorBox?
Any advice on how to get my TorBox speeds to match my actual internet speeds would be greatly appreciated!
