Why does my workspace load slowly?

Workspaces can load slowly when a project has many metrics, runs, or panels. Common causes include high metric counts, excessive panels, too many sections, and large numbers of runs. To restore responsive performance, identify the cause and apply the corresponding fix.

Too many metrics

If your workspace slows down, check whether recent runs have unintentionally logged thousands of new metrics. If they have, consider deleting those runs and recreating them with the desired metrics.

For runs that log between 5,000 and 100,000 metrics, switch to a manual workspace. In manual mode, you can selectively add panels for only the metrics you need to visualize. W&B still collects and stores metrics that aren’t plotted.

Too many panels

If an automatic workspace includes panels for many logged keys, it might load slowly. To fix this, reduce the panel count by switching to manual mode and adding back only the panels you need:

1. Reset the workspace to manual mode.
2. Use Quick add to selectively add panels for the metrics you need.

After you complete these steps, your workspace displays only the panels you explicitly added, which should improve load times.

Deleting unused panels one at a time has little impact on performance. Instead, reset the workspace and selectively add back only those panels you need.

Too many sections

Hundreds of sections can hurt performance. Consider using the workspace setting to create sections by prefix rather than suffix, which can result in fewer, higher-level groupings.

Too many runs

Keep the total number of runs in a single project under 100,000 on W&B Multi-tenant Cloud, or 10,000 on Dedicated Cloud or Self-Managed. If your project exceeds these limits, consider moving less frequently used runs to an archive project.
