BibaVPN, adaptive padding selects a target of roughly 900–1400 bytes for the first seven inner frames. Set max_pad to 64, send a 100-byte payload, and the resulting frame is 169 bytes. The target was 1,200; the padding budget ran out at 64. Here is where those numbers come from. BibaVPN is my experimental SOCKS5/HTTP CONNECT tunnel, written in Rust, with a TLS + WebSocket transport to a server on your own VPS. Its inner frame format reserves five bytes for the header: Byte offset 0
