1 year ago Which platform did you do your testing on? WebRTC can be used both natively and in a web browser. This is an important nuance because the implementation is entirely different.
Please test both native-to-native and native-to-web scenarios to make sure this isn't specific to a single platform.
Also, please upload a minimal reproduction project[^1] to make this easier to troubleshoot.
[^1]: A small Godot project which reproduces the issue, with no unnecessary files included. Be sure to not include the .godot folder in the archive (but keep project.godot).
Drag and drop a ZIP archive to upload it. Do not select another field until the project is done uploading.
Note for C# users: If your issue is not Mono-specific, please upload a minimal reproduction project written in GDScript or VisualScript. This will make it easier for contributors to reproduce the issue locally as not everyone has a Mono setup available.
[Edit] my point is, for exemple, why is a ssh copy ten times faster ?
WebRTC is designed for real-time communication (it's in the name), while SSH is a TCP-based protocol. TCP can do high throughput very well, but struggles at low-latency communication. By contrast, WebRTC is designed for low-latency communication but struggles with delivering high throughput.
If you want to prioritize throughput over latency, use WebSocket or (ideally) HTTP requests. You can keep using both protocols at the same time: WebRTC for real-time needs, HTTP requests to download/upload large files.
As when connected we dont know if we're on turn or real p2p, i tried usine another turn server and the result is the same. Is there optimizations or a way of troubleshootings that i am missing ?
Test on a local network with both machines connected over Ethernet to remove any external conditions.

Issue description
I think my question couldn't be more accurate than :
https://stackoverflow.com/questions/56327783/webrtc-datachannel-for-high-bandwidth-application
TLDR with transfert fonctions already using the max packet size allowed of 256k, my transfert speed on both applications on same network barely reaches 6-7 MB wheres as on remote connection with bandwith equivalent to 20MB , the data transfert will drop somewhere between 300-600 KB ps when it's not almost zero using mobile data with bandwith of 1MB.

Steps to reproduce
Remotely connect webrtc peer, send packets.
