My server is slow when i'm in Korea

Submitted ⁨⁨1⁩ ⁨year⁩ ago⁩ by ⁨Mateleo@lemmy.dbzer0.com⁩ to ⁨selfhosted@lemmy.world⁩

Hi,

I’m currenty using Oracle Free Tier for Jellyfin (hosted in Paris) and i wanted to know what is the proper way to speed up media delivery when i’m far away from the server location ? (Korea currently)

Peering is actually a complex issue. The ISP you’re currently using might not have a good peering with your data center operator.

One way to force a different peering is by complaining to your ISP. Include the server’s IP address in the complain, and their sysadmin might take a look and alter their routing table so traffics going to your data center will go through different route (assuming the ISP is not shitty and have multiple high quality peering AND actually looking at your support request).

Another way is by using a VPN. By using a VPN, you’ll bypass your ISP’s network routing. Your traffic will go through your VPN provider’s data center instead, which have completely different peering partners than your ISP. Try connecting to different country (e.g. Singapore, Hong Kong, Japan, Europe) to see which one is the fastest. For example, your ISP might have a good peering to Hong Kong, so by connecting to a Hong Kong VPN server, you’ll bypass your ISP’s shitty peering to Europe.

  Thank you for your reply! I’ve just tested with my VPN and Hong Kong gives me the best speed. (Like 20x more)

    I was expecting you’ll get like 2x improvement max. 20x is crazy lmao.

  I used to oversee WAN and peering operations for a large multi site. Residential ISPs almost never respond to reports of inefficient routes unless you are one of their peers, big business customers, or you really know your stuff and send in a detailed report showing asymetric routes, bad bgp info, etc.
  
  As far as a VPN goes, that probably wouldn't help either. You will probably increase the number of hops and latency. Your route will still egress your isp gateway, to your VPN provider, then travel over the Internet and to your remote server, while adding additional protocol overhead. Yes, it is remotely possible that there is an improved link from his regional VPN node to his remote provider, but unlikely from my experience with traffic engineering.

    Actually in my case it did help. I got faster speed to one of my VPS in Paris (OVH) if I use VPN to Singapore first. Heck, even my VPS in Singapore (also OVH) is faster too after connecting to the VPN. My ISP probably really have a bad peering with OVH.

    Oh man, fucking tell me about it. I remember Verizon support gave the absolute runaround when I was trying to debug why my server was absolute garbage in San Jose vs LA. Took me 3 separate support calls for them to finally do something about it. It also took me a while to figure out it was an ISP issue in the first place.

Okay, so I have actually lived in Korea and am into self hosting, servers for media, etc.

What I can tell you is, you are fucked. Peering to anywhere other than Japan is a nightmare.

Give up and build your own server in your own home. No amount of peering tricks or CDNs will help you.

The best you’ll get in terms of connections to major service providers is hosting in Dallas, which should get you around 100mbps.

Welcome to the reason why a competitor to YouTube is almost impossible. Network routing is extremely complicated and short of laying your own cables or having multiple points of presence there’s not much you can do about it.

You’re probably limited by your TCP window sizes and congestion control algorithm. Look up a TCP throughput calculator and adjust your window size/congestion control as needed.

If your hosting provider doesn’t grant access to this level, you could try various tunnels, like a UDP VPN that might be more resiliant. Again, not sure how limited you are with your provider. Worst case you could UDP VPN into a server in the same city as your host

  Yeah, I wouldn’t think high latency would be too much for streaming, as long as the client has a decent buffer size and doesn’t wait for a packet to arrive before requesting the next one. What client are you using to play your videos?

    Jellyfin Media Player or the website player

They are limited to 50mbps, as far as I remember, and considering your distance, I would say the ping speeds should be somewhere between 170ms and 250ms.

I've only ever used Oracle cloud in an enterprise environment, so I don't know what features you have available. I'm also much more familiar with AWS. But you should be able to create a proxy endpoint in your present region, and traverse the cloud providers internal network. That would likely improve your streaming. You could also create a VPN endpoint in your current region and terminate your traffic inside your cloud providers network, but that would add protocol overhead.

I would look at tools like iperf to look at your packet loss because being further from your server will increase latency, but shouldn't impact the streaming unless you also have packet loss.

My PeerTube server tube.jeena.net is in Germany and I’m also in Korea, but I don’t really feel any speed problems.

  Ok but isn’t peertube defederated?
  
  Which means (unless I grossly misunderstand the concept)
  
  that your video(s) are stored not only on your own server but also shared out to other servers which also keep a copy cached.
  
  So in this scenario it would be very much immune to these concerns because your video(s) will be streamed from the closest server to you which has a copy, meaning you will always get the best throughput no matter what your physical location is or what it was when you uploaded.

    Ideally yes, but only the public videos are shared with other servers. Most of the videos on my instance are internal, so only people who have an account on it can access the videos.
