meta_leap Are you truly telling me Godot's C++-based UDP networking is faster (or less "troubling") than Godot's C-side stdout/stdin pipes
It might be, depending on what actual i/o streams are abstracted away by stdin and stdout on your target system(s). Printing to console is not without cost either. There are also possible encoding issues. Try to benchmark it.
If you insist on using operating system inter-process communication, better to do it via proper named pipes, especially if exchanged data is plain binary bytes.
