Context

If you're experiencing slow performance when exploring traces in your LangSmith tracing projects, including delays when filtering runs, loading threads, opening traces, or accessing child run inputs/outputs, the issue may be related to the columns being displayed in your trace view. Large data payloads in certain columns can significantly impact browser rendering performance.

Answer

A common cause of slow trace exploration is having the "Metadata" column enabled, which can contain large data payloads that slow down browser rendering.

To resolve this issue:

1. Navigate to your trace project

2. Click the "Columns" button in the trace view

3. Deselect the "Metadata" column to hide it

Hiding columns with large data payloads reduces the rendering load on your browser and should significantly improve UI performance. You can apply this same approach to other columns that may contain large amounts of data.

If you continue to experience performance issues after hiding the Metadata column, consider hiding other columns that may contain large data payloads to further optimize performance.
