Summary

With Remote Control connected via /rc, the local interactive terminal session feels noticeably slower to respond. Immediately after disconnecting with /remote-control, responses become fast again.

Steps to reproduce

  1. Start claude (interactive)
  2. Run /rc to connect Remote Control
  3. Chat locally in the terminal — responses are noticeably delayed
  4. Run /remote-control to disconnect (Remote Control disconnected.)
  5. Responses are fast again

Expected

No perceptible latency penalty on the local session while Remote Control is connected.

Environment

  • Claude Code 2.1.270
  • macOS (Darwin 25.6.0), zsh
  • remoteControlAtStartup not set (RC was enabled manually with /rc)

Notes

Docs say the WebSocket transport keeps latency minimal, but the local slowdown was consistent across the session and disappeared the moment RC was disconnected.
