Description

While testing the Cat-a-lot integration with QuickCategories, I noticed that QuickCategories is currently extremely slow to load, both when opened with URL parameters and even when accessed directly without any parameters (i.e., just opening https://quickcategories.toolforge.org/).

In most cases:

The UI loads partially or takes a long time to render
There’s a noticeable delay even before any request is made
Sometimes the page becomes unresponsive altogether

This makes it difficult to evaluate the integration flow or complete test edits.

I'm filing this in case it's a Toolforge-wide issue or something related to backend slowness. It may not be directly related to QuickCategories code itself, but perhaps debug logs or a restart could help resolve the issue.
