Share
Ongoing Web Updated November 13, 2026Based on 4 user reportsHow we research

Quick answer

Check whether the second page load is fast: if so it is first-load compilation; if not, heavy components on the page layout are the usual cause. Use Lightning Experience Insights and the Analyze button.

Most likely fix: Test a second load and clear the browser

How to fix it

Try these in order — the most common fix is first.

  1. 1. Test a second load and clear the browser

    1. Reload the same record; if it is fast, it was a cold load
    2. Clear cache and cookies, disable extensions, try Chrome
    Did this fix it?

  2. 2. Analyze the page

    1. Open Setup > Lightning Experience Insights or click Analyze in Lightning App Builder
    2. Review slow components and Experience Page Time
    Did this fix it?

  3. 3. Slim the page layout

    1. Move heavy components to non-default tabs
    2. Remove unused related lists and components
    3. Reduce fields on the compact layout
    Did this fix it?

Why it happens
