With delta streaming most websocket frames are tiny per-token deltas, and per-message-deflate pays zlib work on every outgoing frame per subscriber for near-zero gain there; under heavy streaming that shows up as measurable server CPU. The frames that still benefit are the rare large ones (final message, sources), and even a 100k token message is only a few hundred KB uncompressed, which any network delivers without noticeable delay. UVICORN_WS_PER_MESSAGE_DEFLATE=false (default true, current behavior) disables the extension in every entry point: open-webui serve and dev, start.sh both invocations, start_windows.bat and dev.sh. Verified against a running instance: with the flag off the server declines the client-offered permessage-deflate extension, with defaults it still negotiates it.
