Performance back end regression

Created on 21 July 2025, 5 days ago

Overview

In recent version of Experience Builder, it looks like there is a performance regression in the backend responses.
We can experience this slowness specially when there are a lot of components on a page.
For example:

  • GET request to /xb/api/v0/layout/xb_page/14 (loading of the page) took around 8s (with SPX enabled). SPX reported 6M of function calls
  • PATCH request to /xb/api/v0/layout/xb_page/14 (after a prop change) took around 14s (with SPX enabled). SPX reported 11M of function calls


Video of changing prop attached.
