Description

When you have lots of sessions (I currently have around 30), it takes around 2-3 seconds to bring up the session picker and at least 3 or 4 more to switch to another session. Not sure if this is due to the fact that I have two sessions in progress.

OpenCode version

1.0.200

Steps to reproduce

No response

Screenshot and/or share link

No response

Operating System

macos 26.0.1

Terminal

This issue might be a duplicate of existing issues. Please check:

  • #3526: Performance issue: session-child-cycle becomes extremely slow with many sessions

Both issues describe slowness when cycling through multiple sessions using keyboard shortcuts. Feel free to ignore if your specific case differs.
